How do I change the zone offset for a time in Ruby on Rails?

Question

I have a variable foo that contains a time, lets say 4pm today, but the zone offset is wrong, i.e. it is in the wrong time zone. How do I change the time zone?

When Parsing a Time

I'd be interested to hear how you're setting the variable foo to begin with.

If you're parsing a time string that doesn't have a time zone (what I was doing during a data import) then you can use String#in_time_zone to force the time zone during the parsing:

"Fri Jun 26 2019 07:00:00".in_time_zone( "Eastern Time (US & Canada)" ) 
# => Wed, 26 Jun 2019 07:00:00 EDT -04:00

Works like a charm and is super clean.
