# 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
# 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.

# Constructs a Timezone instance for the timezone represented by this
