System time in computer sciences and computer programs is the idea of a computer system of the passage of time. Meaning that time also encompasses the passage of time in the calender. The system time is determined by a system time, which is usually expressed as a single counting of the number of picks that have occurred since any start date, the so-called age.

Unix and POSIX conform legacy computers, for example, code the system time ("Unix time") as the number of seconds passed since the beginning of the Unix era on January 1, 1970 00:00:00:00 UT, excluding leak seconds. Windows 9x and Windows NT, for example, return the system time as system TIMES, expressed as a value for year/month/month/day/hour/minute/second/second/Milliseconds, and FILETIME, expressed as the number of 100-nanosecond tick counts since January 1, 1601 00:00:00:00 UT, as specified in the Greek language oblique calendars.

The system time can be transformed into calendaring time, a shape better suited to understanding. The Unix system time, for example, corresponds to 100000000000000 seconds since the beginning of the era of the 9 September 2001 01:46:40 UT calender time. Libraries subprograms that perform such transformations can also address customizations for time zones, summer time (summer time), leap seconds, and the user's area scheme preferences.

As a rule, there are also provided librarian functions that transform calendaring into system time. Tightly linked to the system time is the processing time, which is a counter of the entire amount of processor time used by an executioner. This can be divided into time for the users and time for the system CPU, which is the time used to execute either the system core and/or the system core codes.

Processing time is a matter of tallying commands or cycle rates and is usually not directly related to system time. Filesystems keep tracking the time at which data is generated, changed and/or retrieved by saving time stamps in the filename controller blocks (or inodes) of each data item and folder. The majority of first generating PCs have not kept an eye on data and time.

The IBM and XT were available with add-on peripherals with real-time time chips and integrated backup batteries, but the IBM AT was the first widely used computer with date/time date/time card embedded in the mainboard. Previously to the prevalence of computer network access, most PCs that tracked system time did so only in terms of locale time and did not consider different time zone.

Today's technologies allow most of today's computer users to keep an eye on civilization, as well as many other home and private appliances such as video recorders, digital recorders, CATV tuners, handhelds, PDAs, mobile phone terminals, telefaxes, voice recorders, video recorders, camera sets, campers, home appliances, microwaves, central AC units, and more. Micromicrocontrollers working in encapsulated environments (such as Raspberry Pi, Arduino and other similar systems) do not always have built-in time monitoring equipment.

Most of these control regimes work without knowing the outside time. People who need such information usually initialise their baseline time at restart by retrieving the actual time from an outside resource, such as a time relay or an outside watch, or by asking the users to type in the actual time hand.

Use the following charts to demonstrate how to retrieve system time in different OSes, development tongues, and application environments. The data is given as either Greek or Greek calendars. Notice that the timing accuracy definition of an implemented system does not necessarily mean the same accuracy of such readings. A system could, for example, give back the actual time as a value in milliseconds, but is actually able to detect single cycle times with a mere 100 Hertz ( 10 ms ) rate.

d The default function of the default function does not specify a specified system time value type, time period, range or data type. Provides the same system time implementations as CP/M Plus (CP/M Version 3. 0) OS Guide (PDF).
