This method is similar to strftime() function defined in ISO C and POSIX.
Several directives (%a, %A, %b, %B, %c, %p, %r, %x, %X, %E*, %O* and %Z)
are locale dependent in the function.
However this method is locale independent.
So, the result may differ even if a same format string is used in other
systems such as C.
It is good practice to avoid %x and %X because there are corresponding
locale independent representations, %D and %T.

Parses date using Date._parse and converts it to a Time object.
If a block is given, the year described in date is converted by the block. For example:
Time.parse(...) {|y| 0 <= y && y < 100 ? (y >= 69 ? y + 1900 : y + 2000) : y}
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:
# 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.
Parses date using Date._strptime and converts it to a Time object.
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}
Below is a list of the formatting options:
The abbreviated weekday name (“Sun”)

Parses date as an HTTP-date defined by RFC 2616 and converts it to a Time object.
ArgumentError is raised if date is not compliant with RFC 2616 or if the Time class cannot represent specified date.
See httpdate for more information on this format.
You must require ‘time’ to use this method.
Returns a string which represents the time as RFC 1123 date of HTTP-date defined by RFC 2616:
day-of-week, DD month-name CCYY hh:mm:ss GMT
Note that the result is always UTC (GMT).
You must require ‘time’ to use this method.
Creates a new Time object with the value given by time, the given number of seconds_with_frac, or seconds and microseconds_with_frac since the Epoch. seconds_with_frac and microseconds_with_frac can be an Integer, Float, Rational, or other Numeric. non-portable feature allows the offset to be negative on some systems.
If a numeric argument is given, the result is in local time.
Time.at(0) #=> 1969-12-31 18:00:00 -0600 Time.at(Time.at(0)) #=> 1969-12-31 18:00:00 -0600 Time.at(946702800) #=> 1999-12-31 23:00:00 -0600 Time.at(-284061600) #=> 1960-12-31 00:00:00 -0600 Time.at(946684800.2).usec #=> 200000 Time.at(946684800, 123456.789).nsec #=> 123456789
Same as Time::gm, but interprets the values in the local time zone.
Time.local(2000,"jan",1,20,15,1) #=> 2000-01-01 20:15:01 -0600
Converts time to local time (using the local time zone in effect for this process) modifying the receiver.
If utc_offset is given, it is used instead of the local time.
t = Time.utc(2000, "jan", 1, 20, 15, 1) #=> 2000-01-01 20:15:01 UTC t.utc? #=> true t.localtime #=> 2000-01-01 14:15:01 -0600 t.utc? #=> false t.localtime("+09:00") #=> 2000-01-02 05:15:01 +0900 t.utc? #=> false
Converts time to UTC (GMT), modifying the receiver.
t = Time.now #=> 2007-11-19 08:18:31 -0600 t.gmt? #=> false t.gmtime #=> 2007-11-19 14:18:31 UTC t.gmt? #=> true t = Time.now #=> 2007-11-19 08:18:51 -0600 t.utc? #=> false t.utc #=> 2007-11-19 14:18:51 UTC t.utc? #=> true
Returns a canonical string representation of time.
Time.now.asctime #=> "Wed Apr 9 08:56:03 2003"
Returns a canonical string representation of time.
Time.now.asctime #=> "Wed Apr 9 08:56:03 2003"
Returns the month of the year (1..12) for time.
t = Time.now #=> 2007-11-19 08:27:30 -0600 t.mon #=> 11 t.month #=> 11
