Time in seconds nowTotal time in seconds now
There is a time stamp in my data base, I have to print it in seconds in EPOC time. Suppose your time stamp is a ruby time object: . If it is a DateTime item, you can use the stringtime and stringtime method.
Gets the number of seconds since the epoch: . Delivers the second since the era containing microseconds: ...... gives back the age. Rummage through other issues marked with rubber on tracks or ask your own one.
Classification of ruby time and date (with examples)
Explore what time-based class rooms and techniques are available in Ruby and how to use them. You can use the time category to control time in Ruby. It is a category representing a date (day/month/year) and a time (hours/minutes/seconds). The time is saved by the time domain as the number of seconds since the epoch, also known as Unix time.
You have several options for initializing a time object. Here is a list of the options. To retrieve an item that displays the actual time, use Time. new or Time. now. It is also possible to use a Unix time stamp and the at methods to build a time item. It is possible to ask a time objects for any of its component parts.
You can, for example, ask which date and months a time objects represents: "This date, is it a Sunday? You can use the zoning methode to verify the actual time zones for a time objects. In this way you get the shortcut for the time area.
You can use the utc_offset methode if you want the time zoneshift. Expenditure for this way is done in seconds, but you can split by 3600 to get it in hrs. CET # "CET" # "CET" # "CET" # "CET" You can also retrieve the actual time in UTC: You may not want the standard time and date strings given to you by the Ruby Time series.
Actually, this way is strictly time, which means'format time'. the time obj. Let us see some examples: time. strftime("%d/%m/%Y") x × x w # "05/12/2015" time. strftime("%k:%M") x x w x w x # w x w x w x w x w x "17:48" time. strftime("Today is %A ") x x w x w x "Today is Sunday" time. strftime("%d of %B, %Y") x w x w 21 of December 2015" time.
strftime ("Unix time is %s") # Unix time is 1449336630" time. strftime("%d/%m/%Y") # 05/12/2015 " time. strftime("%k:%M") # 17:48 " time. strftime("Today is %A ") # Today is Sunday time.
The time can be displayed without a date or a beautifully styled date with the year, date and name of the actual monthly.
You sometimes don't want the present time, but a time in the past or in the now. Add time items with time items! Keep in mind that the time is displayed internally in seconds so you can do this: This example shows a time item that is 10 seconds away from the time.
You can then see if that time has expired. When you want to get something like what happened last night, you have to compute how many seconds there are in a single second. We can now use this number to read from the actual date: if you use Rails, you can do that:
Date classes have no idea of minute, second or hour. Everything in this category is stored in the form of internal storage units. In order to use the date category, you need the date. Use Date.today to display the date. Contrary to time, Date New is not an a. k. a. a. for today, so remember.
The datearithmetic is similar to the time category, the exception being that you are adding dates instead of seconds. File knows nothing about lessons, seconds, or even minutes, so use this category only when you don't need it. Time can be analyzed using the time category. It will take time to activate this feature.
Here is an example: ' must time' must'time' must'time' require' time' must'time' If you want to specify the form of your entry string, you can use the stringtime approach. So: require'time' require' time' require ' time' require' Time' require'time' The only distinction between Time. parase & date. parase is the type of item you get back (Time or Date).
There are some constant values in the Date category that you may find useful. Fridays begin on Sunday, but you can use the rotation technique to make the weekly begin on Monday. DateTime classes are subclasses of Date and can save seconds as well as date. Example: required'date' require' date'date' require' date' require' date'date' Both Time and DateTime can do the same thing, with the major exception that Time is written in C, so it will be quicker.
They are not available in ruby only, they are added by the ActiveSupport components of Rails. Below are some samples, note that these method do not revert to time or date object, but revert to a user-defined ActiveSupport category. So you can do time with these things and get things like tomorrow's date:
