time_zone_select

Return select and option tags for the given object and method, using #time_zone_options_for_select to generate the list of option tags.

In addition to the :include_blank option documented above, this method also supports a :model option, which defaults to ActiveSupport::TimeZone. This may be used by users to specify a different time zone model object. (See time_zone_options_for_select for more information.)

You can also supply an array of ActiveSupport::TimeZone objects as priority_zones, so that they will be listed above the rest of the (long) list. (You can use ActiveSupport::TimeZone.us_zones as a convenience for obtaining a list of the US time zones, or a Regexp to select the zones of your choice)

Finally, this method supports a :default option, which selects a default ActiveSupport::TimeZone if the object’s time zone is nil.

time_zone_select( "user", "time_zone", nil, include_blank: true)

time_zone_select( "user", "time_zone", nil, default: "Pacific Time (US & Canada)" )

time_zone_select( "user", 'time_zone', ActiveSupport::TimeZone.us_zones, default: "Pacific Time (US & Canada)")

time_zone_select( "user", 'time_zone', [ ActiveSupport::TimeZone['Alaska'], ActiveSupport::TimeZone['Hawaii'] ])

time_zone_select( "user", 'time_zone', /Australia/)

time_zone_select( "user", "time_zone", ActiveSupport::TimeZone.all.sort, model: ActiveSupport::TimeZone)
