def period_for_utc(utc)
  raise_not_implemented('period_for_utc')
end

#periods_for_local(local) ⇒ Object

Returns the set of TimezonePeriods for the given local time as an array.

Results returned are ordered by increasing UTC start date. Returns an empty array if no periods are found for the given time.

end

#transitions_up_to(utc_to, utc_from = nil) ⇒ Object

Returns an Array of TimezoneTransition instances representing the times where the UTC offset of the timezone changes.

Transitions are returned up to a given date and time up to a given date and time, specified in UTC (utc_to).

A from date and time may also be supplied using the utc_from parameter (also specified in UTC). If utc_from is not nil, only transitions from that date and time onwards will be returned.

Comparisons with utc_to are exclusive. Comparisons with utc_from are inclusive. If a transition falls precisely on utc_to, it will be excluded. If a transition falls on utc_from, it will be included.

Transitions returned are ordered by when they occur, from earliest to latest.

utc_to and utc_from can be specified using either DateTime, Time or integer timestamps (Time.to_i).

If utc_from is specified and utc_to is not greater than utc_from, then transitions_up_to raises an ArgumentError exception.
