Returns the simultaneous time in Time.zone
if a zone is given or if Time.zone_default
is set. Otherwise, it returns the current time.
Time.zone = 'Hawaii' # => 'Hawaii' Time.utc(2000).in_time_zone # => Fri, 31 Dec 1999 14:00:00 HST -10:00 Date.new(2000).in_time_zone # => Sat, 01 Jan 2000 00:00:00 HST -10:00
This method is similar to Time#localtime, except that it uses Time.zone
as the local zone instead of the operating system's time zone.
You can also pass in a TimeZone instance or string that identifies a TimeZone as an argument, and the conversion will be based on that zone instead of Time.zone
.
Time.utc(2000).in_time_zone('Alaska') # => Fri, 31 Dec 1999 15:00:00 AKST -09:00 Date.new(2000).in_time_zone('Alaska') # => Sat, 01 Jan 2000 00:00:00 AKST -09:00
