Display UTC based on known timezone

If I 开发者_StackOverflow社区know the Time.zone e.g. London, any ideas on how I can display

(GMT+00:00) London

without assigning

Time.zone = "London"

and then calling

puts Time.zone

Thanks in advance!

You can call:

Time.zone.formatted_offset

Which will:

returns the offset of this time zone as a formatted string, of the format “+HH:MM”.

per: http://api.rubyonrails.org/classes/ActiveSupport/TimeZone.html#method-i-formatted_offset

So if you wanted to format the string, you could do:

"GMT(#{Time.zone.formatted_offset})"

The to_s method provides exactly this output.

Time.zone.to_s
# => "(GMT+00:00) London"
