# Return the number of seconds the specified time zone differs

# Numeric time zones that include minutes, such as

# simpler hour-only time zones like -10 or
# +13.
#
# Textual time zones listed in ZoneOffset are also supported.
#
# If the time zone does not match any of the above, +zone_offset+
# will check if the local time zone (both with and without
# potential Daylight Saving \Time changes being in effect) matches
# +zone+. Specifying a value for +year+ will change the year used
# to find the local time zone.
#
# If +zone_offset+ is unable to determine the offset, nil will be
# returned.

# Time.parse("12:00") #=> 2011-10-31 12:00:00 -0500
#
# We can change the date used to infer our missing elements by passing a second

# We can also use our own object.

#
# If a block is given, the year described in +date+ is converted
# by the block. This is specifically designed for handling two
# digit years. For example, if you wanted to treat all two digit
# years prior to 70 as the year 2000+ you could write this:
#
# require 'time'
#
# Time.parse("01-10-31") {|year| year + (year < 70 ? 2000 : 1900)}
# #=> 2001-10-31 00:00:00 -0500
# Time.parse("70-10-31") {|year| year + (year < 70 ? 2000 : 1900)}
# #=> 1970-10-31 00:00:00 -0500
#
# If the upper components of the given time are broken or missing, they are
# supplied with those of +now+. For the lower components, the minimum
# values (1 or 0) are assumed if broken or missing. For example:
#
# require 'time'
#
# # Suppose it is "Thu Nov 29 14:33:20 2001" now and
# # your time zone is EST which is GMT-5.
# now = Time.parse("Thu Nov 29 14:33:20 2001")
# Time.parse("16:30", now) #=> 2001-11-29 16:30:00 -0500
# Time.parse("7/23", now) #=> 2001-07-23 00:00:00 -0500
# Time.parse("Aug 31", now) #=> 2001-08-31 00:00:00 -0500
# Time.parse("Aug 2000", now) #=> 2000-08-01 00:00:00 -0500
#
# Since there are numerous conflicts among locally defined time zone
# abbreviations all over the world, this method is not intended to
# understand all of them. For example, the abbreviation "CST" is
# used variously as:
#
# -06:00 in America/Chicago,
# -05:00 in America/Havana,
# +08:00 in Asia/Harbin,
# +09:30 in Australia/Darwin,
# +10:30 in Australia/Adelaide,
# etc.
#
# Based on this fact, this method only understands the time zone
# abbreviations described in RFC 822 and the system time zone, in the
# order named. (i.e. a definition in RFC 822 overrides the system
# time zone definition.) The system time zone is taken from
# Time.local(year, 1, 1).zone and
# Time.local(year, 7, 1).zone.
# If the extracted time zone abbreviation does not match any of them,
# it is ignored and the given time is regarded as a local time.
#
# ArgumentError is raised if Date._parse cannot extract information from
# +date+ or if the Time class cannot represent specified date.
#
# This method can be used as a fail-safe for other parsing methods as:
#
# Time.rfc2822(date) rescue Time.parse(date)
# Time.httpdate(date) rescue Time.parse(date)
# Time.xmlschema(date) rescue Time.parse(date)
#
# A failure of Time.parse should be checked, though.
#
# You must require 'time' to use this method.

def self.parse: (String date, ?_TimeLike now) ?{ (Integer) -> Integer } -> Time
#
# Works similar to +parse+ except that instead of using a
# heuristic to detect the format of the input string, you provide
# a second argument that describes the format of the string.
#
# If a block is given, the year described in +date+ is converted by the
# block. For example:
#
# Time.strptime(...) {|y| y < 100 ? (y >= 69 ? y + 1900 : y + 2000) : y}
