+# Get Formatted UTC Offset Value
+
+The UTC offset (during DST) for Chicago is `-05:00`. And for Newfoundland it is
+`-02:30`.
+
+Rails has an [`ActiveSupport::TimeZone`
+module](https://api.rubyonrails.org/v7.1.3.2/classes/ActiveSupport/TimeZone.html#method-c-seconds_to_utc_offset)
+that can turn the UTC offset in seconds into this formatted value.
+
+```ruby
+> chicago = TZInfo::Timezone.get('America/Chicago')
+=> #<TZInfo::DataTimezone: America/Chicago>
+> ActiveSupport::TimeZone.seconds_to_utc_offset(chicago.utc_offset)
+=> "-05:00"
+
+> newfoundland = TZInfo::Timezone.get('America/St_Johns')
+=> #<TZInfo::DataTimezone: America/St_Johns>
+> ActiveSupport::TimeZone.seconds_to_utc_offset(newfoundland.utc_offset)
+=> "-02:30"
+```
+
+The underlying `tzinfo` gem is DST-aware and its database even knows which time
+zone identifiers don't observe DST, so you can run this anytime of the year and
+expect reliable results.
+
+Here is another way at this:
+
+```ruby
+> chicago = TZInfo::Timezone.get('America/Chicago')
+=> #<TZInfo::DataTimezone: America/Chicago>
+> ActiveSupport::TimeZone[chicago.name]
+=> #<ActiveSupport::TimeZone:0x00000001099d8140 @name="America/Chicago", @tzinfo=#<TZInfo::DataTimezone: America/Chicago>, @utc_offset=nil>
+> ActiveSupport::TimeZone[chicago.name].formatted_offset
+=> "-06:00"
+> ActiveSupport::TimeZone[chicago.name].formatted_offset(false)
+=> "-0600"
+```
