I have a string like this:
"2010-01-01 12:30:00"
I need that to convert to UTC from the current local time zone.
I tried this, but it seems to think that the string is already UTC.
"2010-01-01 12:30:00".to_datetime.in_time_zone("Central Time (US & Canada)")
=> Fri, 01 Jan 2010 06:30:00 CST -06:00
I am not sure where to go from here.
added this from my comment:
>> Time.zone = "Pacific Time (US & Canada)"
=> "Pacific Time (US & Canada)"
>> Time.parse("2010-10-27 00:00:00").getutc
=> Wed Oct 27 06:00:00 UTC 2010
>> Time.zone = "Mountain Time (US & Canada)"
=> "Mountain Time (US & Canada)"
>> Time.parse("2010-10-27 00:00:00").getutc
=> Wed Oct 27 06:00:00 UTC 2010
Thanks for any help.

Time.parse("2010-01-01 12:30:00").getutc
EDIT
(grinding teeth while thinking about the nightmare which is Ruby/Rails date/time handling)
OK, how about this:
Time.zone.parse("2010-01-01 12:30:00").utc
Note that Time.zone.parse
returns a DateTime
, while appending the .utc
gives you a Time
. There are differences, so beware.
Also, Time.zone is part of Rails (ActiveSupport), not Ruby. Just so you know.

In Rails 4 and above you can directly use in_time_zone
"2010-01-01 12:30:00".in_time_zone
#=> Fri, 01 Jan 2010 12:30:00 EST -05:00
"2010-01-01 12:30:00".in_time_zone.utc
#=> 2010-01-01 17:30:00 UTC

For APIs you can use:
utc_date = Time.parse("2013-05-31 00:00").utc.iso8601 #=> Result will be: 2013-05-30T21:00:00Z
