# <!-- rdoc-file=timev.rb -->
# Time is an abstraction of dates and times. Time is stored internally as the
# number of seconds with subsecond since the *Epoch*, 1970-01-01 00:00:00 UTC.
#
# The Time class treats GMT (Greenwich Mean Time) and UTC (Coordinated Universal
# Time) as equivalent. GMT is the older way of referring to these baseline times
# but persists in the names of calls on POSIX systems.
#
# Note: A Time object uses the resolution available on your system clock.
#
# All times may have subsecond. Be aware of this fact when comparing times with
# each other -- times that are apparently equal when displayed may be different
# when compared. (Since Ruby 2.7.0, Time#inspect shows subsecond but Time#to_s
# still doesn't show subsecond.)
#
# ## Examples
#
# All of these examples were done using the EST timezone which is GMT-5.
#
# ### Creating a New Time Instance
#
# You can create a new instance of Time with Time.new. This will use the current
# system time. Time.now is an alias for this. You can also pass parts of the
# time to Time.new such as year, month, minute, etc. When you want to construct
# a time this way you must pass at least a year. If you pass the year with
# nothing else time will default to January 1 of that year at 00:00:00 with the
# current system timezone. Here are some examples:
#
# Time.new(2002) #=> 2002-01-01 00:00:00 -0500
# Time.new(2002, 10) #=> 2002-10-01 00:00:00 -0500
# Time.new(2002, 10, 31) #=> 2002-10-31 00:00:00 -0500
#
# You can pass a UTC offset:
#
# Time.new(2002, 10, 31, 2, 2, 2, "+02:00") #=> 2002-10-31 02:02:02 +0200
#
# Or a timezone object:
#
# zone = timezone("Europe/Athens") # Eastern European Time, UTC+2
# Time.new(2002, 10, 31, 2, 2, 2, zone) #=> 2002-10-31 02:02:02 +0200
#
# You can also use Time.local and Time.utc to infer local and UTC timezones
# instead of using the current system setting.
#
# You can also create a new time using Time.at which takes the number of seconds
# (with subsecond) since the [Unix
# Epoch](https://en.wikipedia.org/wiki/Unix_time).
#
# Time.at(628232400) #=> 1989-11-28 00:00:00 -0500
#
# ### Working with an Instance of Time
#
# Once you have an instance of Time there is a multitude of things you can do
# with it. Below are some examples. For all of the following examples, we will
# work on the assumption that you have done the following:
#
# t = Time.new(1993, 02, 24, 12, 0, 0, "+09:00")
#
# Was that a monday?
#
# t.monday? #=> false
#
# What year was that again?
#
# t.year #=> 1993
#
# Was it daylight savings at the time?
#
# t.dst? #=> false
#
# What's the day a year later?
#
# t + (60*60*24*365) #=> 1994-02-24 12:00:00 +0900
#
# How many seconds was that since the Unix Epoch?
#
# t.to_i #=> 730522800
#
# You can also do standard functions like compare two times.
#
# t1 = Time.new(2010)
# t2 = Time.new(2011)
#
# t1 == t2 #=> false
# t1 == t1 #=> true
# t1 < t2 #=> true
# t1 > t2 #=> false
#
# Time.new(2010,10,31).between?(t1, t2) #=> true
#
# ## What's Here
#
# First, what's elsewhere. Class Time:
#
# * Inherits from [class
# Object](Object.html#class-Object-label-What-27s+Here).
# * Includes [module
# Comparable](Comparable.html#module-Comparable-label-What-27s+Here).

#
#
# ## Timezone Argument
#
# A timezone argument must have `local_to_utc` and `utc_to_local` methods, and
# may have `name`, `abbr`, and `dst?` methods.
#
# The `local_to_utc` method should convert a Time-like object from the timezone
# to UTC, and `utc_to_local` is the opposite. The result also should be a Time
# or Time-like object (not necessary to be the same class). The #zone of the
# result is just ignored. Time-like argument to these methods is similar to a
# Time object in UTC without subsecond; it has attribute readers for the parts,
# e.g. #year, #month, and so on, and epoch time readers, #to_i. The subsecond
# attributes are fixed as 0, and #utc_offset, #zone, #isdst, and their aliases
# are same as a Time object in UTC. Also #to_time, #+, and #- methods are
# defined.
#
# The `name` method is used for marshaling. If this method is not defined on a
# timezone object, Time objects using that timezone object can not be dumped by
# Marshal.
#
# The `abbr` method is used by '%Z' in #strftime.
#
# The `dst?` method is called with a `Time` value and should return whether the
# `Time` value is in daylight savings time in the zone.
#
# ### Auto Conversion to Timezone
#
# At loading marshaled data, a timezone name will be converted to a timezone
# object by `find_timezone` class method, if the method is defined.
#
# Similarly, that class method will be called when a timezone argument does not
# have the necessary methods mentioned above.

# %G - The week-based year
# %g - The last 2 digits of the week-based year (00..99)
# %V - Week number of the week-based year (01..53)
#
# Week number:
# The first week of YYYY that starts with a Sunday or Monday (according to %U

# %D - Date (%m/%d/%y)
# %F - The ISO 8601 date format (%Y-%m-%d)
# %v - VMS date (%e-%^b-%4Y)
# %x - Same as %D
# %X - Same as %T
# %r - 12-hour time (%I:%M:%S %p)
# %R - 24-hour time (%H:%M)
# %T - 24-hour time (%H:%M:%S)
#
# This method is similar to strftime() function defined in ISO C and POSIX.
#
# While all directives are locale independent since Ruby 1.9, %Z is platform
# dependent. So, the result may differ even if the same format string is used in
# other systems such as C.
#
# %z is recommended over %Z. %Z doesn't identify the timezone. For example,
# "CST" is used at America/Chicago (-06:00), America/Havana (-05:00),
# Asia/Harbin (+08:00), Australia/Darwin (+09:30) and Australia/Adelaide
# (+10:30). Also, %Z is highly dependent on the operating system. For example,
# it may generate a non ASCII string on Japanese Windows, i.e. the result can be
# different to "JST". So the numeric time zone offset, %z, is recommended.
