|time2str( [$time] )||
The time2str() function converts a machine time (seconds since epoch)
to a string. If the function is called without an argument or with an
undefined argument, it will use the current time.
The string returned is in the format preferred for the HTTP protocol. This is a fixed length subset of the format defined by RFC 1123, represented in Universal Time (GMT). An example of a time stamp in this format is:
|str2time( $str [, $zone] )||
The str2time() function converts a string to machine time. It returns
undef if the format of $str is unrecognized, otherwise whatever the
Time::Local functions can make out of the parsed time. Dates
before the systems epoch may not work on all operating systems. The
time formats recognized are the same as for parse_date().
The function also takes an optional second argument that specifies the default time zone to use when converting the date. This parameter is ignored if the zone is found in the date string itself. If this parameter is missing, and the date string format does not contain any zone specification, then the local time zone is assumed.
If the zone is not "GMT or numerical (like -0800 or +0100"), then the Time::Zone module must be installed in order to get the date recognized.
|parse_date( $str )||
This function will try to parse a date string, and then return it as a
list of numerical values followed by a (possible undefined) time zone
specifier; ($year, $month, $day, $hour, $min, $sec, $tz). The $year
will be the full 4-digit year, and $month numbers start with 1 (for January).
In scalar context the numbers are interpolated in a string of the YYYY-MM-DD hh:mm:ss TZ-format and returned.
If the date is unrecognized, then the empty list is returned (undef in scalar context).
The function is able to parse the following formats:
The parser ignores leading and trailing whitespace. It also allow the seconds to be missing and the month to be numerical in most formats.
If the year is missing, then we assume that the date is the first matching date before current month. If the year is given with only 2 digits, then parse_date() will select the century that makes the year closest to the current date.
|time2iso( [$time] )||Same as time2str(), but returns a YYYY-MM-DD hh:mm:ss-formatted string representing time in the local time zone.|
|time2isoz( [$time] )||Same as time2str(), but returns a YYYY-MM-DD hh:mm:ssZ-formatted string representing Universal Time.|
