Current Time Clock with secondsActual timer with second display
Watch (Java platform SE 8)
Determines a clock that retrieves moments from the specified clock, which is shortened to the next appearance of the specified time. The clock is ticking only according to the indicated time. So if the time is half a second, the watch gives back moments that have been shortened to half a second. Tipp durations must be negative.
When it has a part smaller than a whole milisecond, then the whole length must be divided into one second without left a part. However, all standard ticks meet these requirements, multiples of hour, minute, second and milisecond as well as reasonable nano second times such as 20-ns, 250,000ns and 500,000ns.
Zero or one nano second would have no cutting effect. If you pass one of them, the clock on which it is based is reset. Therefore, it is possible that the beginning of the required period monitored over this clock is later than the beginning of the direct observation over the watch underneath. Returns an unchangeable, thread-safe and serializable implement, as long as it is the basic clock.
Timeshare and Conversions
The majority of the features set out in this plugin call the features of the same name from Plattform C2. Time is the point at which time begins. January 1 of this year, at midnight, the "time since the epoch" is zero. Unix sees the 1970s as the time. In order to find out what the era is, look at gmtime(0).
Features in this modul do not deal with data and periods before the era or far into the distant future. 2. It is Coordinated Universal Time (formerly known as Greenwich Mean Time, or GMT for short). The DST is summer time, an adaptation of the time zone by (usually) one full hours during part of the year.
Summer time regulations are magical (according to applicable laws ) and may vary from year to year. Because the C libary has a spreadsheet with locale values (often taken from a system script due to flexibility), it is the only true wisdom resource in this area. Accuracy of the various real-time function may be less than proposed by the entities in which their value or arguments are express.
For example, on most Unix computers the clock "ticks" only 50 or 100 Times per second. However, the accuracy of time() and sleep() is better than their Unix equivalents: timings are given as floats, time() gives back the most exact time available (with Unix gettimeofday() if available), and sleep() accepts a time with a non-zero break (Unix select() is used to do this if available).
And the time value given back by gmtime(), localtime() and strptime() and acceptable by asctime(), mktime() and strftime() can be regarded as a series of 9 whole numbers. Returns gmtime(), localtime() and strptime() also provide attributes for single field name. Modified in release 2. 2: The time value order was modified from a Tupel to a struct_time, with additional attributes name for the field.
You can use the following features to switch between time displays: You can also change it at runtime. This is the offsets of the daylight saving time zone, in seconds westward of downtown UTC, if any. Note that this is not the case if the summer time zone is situated just outside eastward direction of ETC (as in Western Europe, Britain included).
Converts a struct_time or Tupel that represents a time passed by gmtime() or localtime() into a 24-digit character chain of the following form: Otherwise, the current time passed by localtime() is used. Modified to 2. Under Unix, the current CPU time is given as a decimal point number in seconds.
Under Windows this feature will return the seconds of the clock that have passed since the first call of this feature as a decimal point number, using the Win32 QueryPerformanceCounter() feature. Translate a time in seconds since the era into a character chain that represents the area time. is not specified or None, the current time will be used that is given back by time(). ctime(secs) corresponds to asctime(localtime(secs)).
Modified to 2. Modified to 2. 4: If seconds is None, the current time is used. Converts a time in seconds since the era into a struct_time value in utility time where the decimal point is always zero. is not specified or None, the current time is used, which is passed back by time().
Modified to 2. Modified to 2. 4: If seconds is None, the current time is used. The same as gmtime(), but converted to locale time. is not specified or None, the current time is used, which is passed back by time(). Sets the daylight saving time to 1 if it is valid for the specified time.
Modified to 2. Modified to 2. 4: If seconds is None, the current time is used. It is the reverse feature of localtime(). It' s arguement is the struct_time or full 9 tuple (since the gst flags are needed; use -1 as the gst flags if it is unknown) which will express the time in locale time and not unTC.
It can be a floating-point number to specify a more accurate sleeping time. Exposure time may be shorter than required because each detected pulse terminates the sleep() after the detection of that pulse.
In addition, due to the planning of other activities in the system, the interruption time can be any amount longer than required. Converts a Tupel or struct_time that represents a time passed by gmtime() or localtime() to a character set by the form arguments. Otherwise, the current time given by localtime() is used. The file must be a substring.
Modified to 2. Modified to 2. Modified to 2. 5: 0 is now a juridical reason for each item in the timeuple; if it is normally unlawful, the value is set to a proper item. You can embed the following statements in the form strings. %cLocale's appropriate date and time notation.
Hysteresis (24-hour clock) as hexadecimal number[00,23]. %IHour (12-hour clock) as hexadecimal number[01,12]. %XLocale's appropriate time notation. %Year with cent as hexadecimal number. %ZTTtime area name ( no character if there is no time area). If used with the strptime() feature, the %p utility will only affect the issue hours if the %I utility is used to parent the time.
Actually the real value is between 0 and 61; this explains leak seconds and the (very rare) twice leak seconds. If used with the strptime() method, %U and %W are only used in computations if the weekday and year are specified. "%a, %b %Y %H:%M:%S +0000",'Thu, 28 Jun 2001 14:17:15 +0000' Extra directives may be available on certain plattforms, but only those mentioned here have a standard ANSI C significance. To see the full list of formats code support on your plattforms, see the strftime(3) document.
Normally the panel width is 2, except %j where it is 3. Parse a character string that represents a time according to a specified size. Returns a struct_time as it is given by gmtime() or localtime(). It uses the same statements as strftime(); by default, it is set to "%a %b %d %H:%M:%S %YY", which is the same as the default value given by ctime().
ValueError is triggered if character strings cannot be formatted correctly or if they contain surplus information after they have been formatted. "Struct_time (tm_year=2000, tm_mon=11, us_mday=30, tm_hour=0, tm_min=0, tm_min=0, tm_min=0, The substitution of the %Z direction is done on the basis of the value included in username and whether light is truth.
This is the time value order types returning from gmtime(), localtime() and strptime(). It' an entity with a titled Tupel interface: you can access a value by its index and name. News in 2.2 now. When calling mktime(), tm_isdst can be 1 if summer time is enabled and 0 if it is not enabled.
A TypeError is triggered when a task with the invalid length is transferred to a task that expects struct_time or has items of the invalid length. Returns the time in seconds since the era as a decimal point number. Notice that although time is always given back as a float, not all instruments deliver time with better accuracy than 1 second.
Whilst this feature normally does not give back declining numbers, it may give back a lower value than a prior call if the system clock was reset between the two callbacks. This is the time zone offsets of the non-DST time zone, in seconds westwards of downtown CT (negative in most Western European countries, favorable in the US, zero in the UK).
The first is the name of the non-DST time zone, the second is the name of the DST time zone. Resets the time change rule used by the libraries routine. You can also change the values of the tags of the time zone (from the TZ environmental tag), time zone (non-DST seconds western of UTC), old zone (DST seconds western of UTC), and natural light (to 0 if this time zone has no summer time rule, or to non-zero if there is a time, past, present, or present if summer time applies).
News in 2.3 release. While in many cases modifying the TZ environmental variables can influence the performance of a function such as localtime() without invoking tzset(), you should not rely on this behaviour. TZ environmental variables have the default size (spaces added for better clarity): One of the following is the starting and ending date format:
Tag zero is Sunday. Time has the same size as offsets, except that no prefix ('-' or'+') is permitted. If the time is not specified, the preset is 02:00:00:00. Territory settings affect the way many formats are interpreted in strftime() and strptime(). Modulkalender General calender related function. timegm() is the opposite of gmtime() from this modul.
