Type:
Class
A Time-like class that can represent a time in any
time zone. Necessary because standard Ruby Time
instances are limited to UTC and the system's ENV['TZ']
zone.
You shouldn't ever need to create a TimeWithZone instance directly via
new. Instead use methods local,
parse, at and now on TimeZone instances, and in_time_zone
on Time and DateTime instances.
1 2 3 4 5 6 | Time.zone = 'Eastern Time (US & Canada)' # => 'Eastern Time (US & Canada)'Time.zone.local(2007, 2, 10, 15, 30, 45) # => Sat, 10 Feb 2007 15:30:45 EST -05:00Time.zone.parse('2007-02-10 15:30:45') # => Sat, 10 Feb 2007 15:30:45 EST -05:00Time.zone.at(1170361845) # => Sat, 10 Feb 2007 15:30:45 EST -05:00Time.zone.now # => Sun, 18 May 2008 13:07:55 EDT -04:00Time.utc(2007, 2, 10, 20, 30, 45).in_time_zone # => Sat, 10 Feb 2007 15:30:45 EST -05:00 |
See Time and TimeZone for further documentation of these methods.
TimeWithZone instances implement the same API as Ruby Time instances, so that Time and TimeWithZone instances are interchangeable.
