# Rails TimeZone object (e.g., "Central Time (US & Canada)"), or a TZInfo::Timezone object
#
# Any Time or DateTime object can use this default time zone, via #in_current_time_zone.
# Example:
#
# Time.zone = 'Hawaii' # => 'Hawaii'
# Time.utc(2000).in_current_time_zone # => Fri, 31 Dec 1999 14:00:00 HST -10:00

# t.in_time_zone('Alaska') # => Fri, 31 Dec 1999 15:00:00 AKST -09:00
