|
|

|
|
* Time.utc(sec, min, hour, mday, month, year, dummy, dummy, dummy, dummy)

|
|
* Time.utc(*a) # => 0005-04-03 02:01:00 UTC
|
|
*
|
|
* This form is useful for creating a \Time object from a 10-element
|
|
* array returned by Time.to_a:
|
|
*
|
|
* t = Time.new(2000, 1, 2, 3, 4, 5, 6) # => 2000-01-02 03:04:05 +000006
|

|
|
* Time.utc(*a) # => 2000-01-02 03:04:05 UTC
|
|
*
|
|
* The two forms have their first six arguments in common,
|
|
* though in different orders;
|
|
* the ranges of these common arguments are the same for both forms; see above.
|
|
*
|
|
* Raises an exception if the number of arguments is eight, nine,
|
|
* or greater than ten.
|
|
*

|
* Time.gm is an alias for Time.utc.

|
|
* %::z - hour, minute and second offset from UTC (e.g. +09:00:00)
|
|
* %Z - Abbreviated time zone name or similar information. (OS dependent)
|
|
*
|
|
* Weekday:
|
|
* %A - The full weekday name (``Sunday'')
|
|
* %^A uppercased (``SUNDAY'')
|
|
* %a - The abbreviated name (``Sun'')
|
|
* %^a uppercased (``SUN'')
|
|
* %u - Day of the week (Monday is 1, 1..7)
|
|
* %w - Day of the week (Sunday is 0, 0..6)
|
|
*
|
|
* ISO 8601 week-based year and week number:
|
|
* The first week of YYYY starts with a Monday and includes YYYY-01-04.
|
|
* The days in the year before the first week are in the last week of
|
|
* the previous year.
|
|
* %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
|
|
* or %W). The days in the year before the first week are in week 0.
|
|
* %U - Week number of the year. The week starts with Sunday. (00..53)
|
|
* %W - Week number of the year. The week starts with Monday. (00..53)
|
|
*
|
|
* Seconds since the Epoch:
|
|
* %s - Number of seconds since 1970-01-01 00:00:00 UTC.
|
|
*
|
|
* Literal string:
|
|
* %n - Newline character (\n)
|
|
* %t - Tab character (\t)
|
|
* %% - Literal ``%'' character
|
|
*
|
|
* Combination:
|
|
* %c - date and time (%a %b %e %T %Y)
|
|
* %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.
|
|
*
|
|
* Examples:
|
|
*
|
|
* t = Time.new(2007,11,19,8,37,48,"-06:00") #=> 2007-11-19 08:37:48 -0600
|
|
* t.strftime("Printed on %m/%d/%Y") #=> "Printed on 11/19/2007"
|
|
* t.strftime("at %I:%M %p") #=> "at 08:37 AM"
|
|
*
