Sequel doesn't pay much attention to timezones by default, but you can set it handle timezones if you want. There are three separate timezone settings, application_timezone, database_timezone, and typecast_timezone. All three timezones have getter and setter methods. You can set all three timezones to the same value at once via Sequel.default_timezone=.
The only timezone values that are supported by default are :utc (convert to UTC), :local (convert to local time), and nil (don't convert). If you need to convert to a specific timezone, or need the timezones being used to change based on the environment (e.g. current user), you need to use the named_timezones extension (and use DateTime as the datetime_class). Sequel also ships with a thread_local_timezones extensions which allows each thread to have its own timezone values for each of the timezones.
The timezone you want the application to use. This is the timezone that incoming times from the database and typecasting are converted to.
The timezone that incoming data that Sequel needs to typecast is assumed to be already in (if they don't include an offset).
Convert the given Time/DateTime object into the database timezone, used when literalizing objects in an SQL string.
# File lib/sequel/timezones.rb, line 38 def application_to_database_timestamp(v) convert_output_timestamp(v, Sequel.database_timezone) end
Converts the object to the given output_timezone.
# File lib/sequel/timezones.rb, line 43 def convert_output_timestamp(v, output_timezone) if output_timezone if v.is_a?(DateTime) case output_timezone when :utc v.new_offset(0) when :local v.new_offset(local_offset_for_datetime(v)) else convert_output_datetime_other(v, output_timezone) end else v.send(output_timezone == :utc ? :getutc : :getlocal) end else v end end
Converts the given object from the given input timezone to the application_timezone using convert_input_timestamp and convert_output_timestamp.
# File lib/sequel/timezones.rb, line 65 def convert_timestamp(v, input_timezone) begin if v.is_a?(Date) && !v.is_a?(DateTime) # Dates handled specially as they are assumed to already be in the application_timezone if datetime_class == DateTime DateTime.civil(v.year, v.month, v.day, 0, 0, 0, application_timezone == :local ? (defined?(Rational) ? Rational(Time.local(v.year, v.month, v.day).utc_offset, 86400) : Time.local(v.year, v.month, v.day).utc_offset/86400.0) : 0) else Time.send(application_timezone == :utc ? :utc : :local, v.year, v.month, v.day) end else convert_output_timestamp(convert_input_timestamp(v, input_timezone), application_timezone) end rescue InvalidValue raise rescue => e raise convert_exception_class(e, InvalidValue) end end
Convert the given object into an object of Sequel.datetime_class in the application_timezone. Used when converting datetime/timestamp columns returned by the database.
# File lib/sequel/timezones.rb, line 87 def database_to_application_timestamp(v) convert_timestamp(v, Sequel.database_timezone) end
Sets the database, application, and typecasting timezones to the given timezone.
# File lib/sequel/timezones.rb, line 92 def default_timezone=(tz) self.database_timezone = tz self.application_timezone = tz self.typecast_timezone = tz end
Convert the given object into an object of Sequel.datetime_class in the application_timezone. Used when typecasting values when assigning them to model datetime attributes.
# File lib/sequel/timezones.rb, line 101 def typecast_to_application_timestamp(v) convert_timestamp(v, Sequel.typecast_timezone) end
