dm_date

DM_DATE(1)						User Contributed Perl Documentation						DM_DATE(1)

NAME

       dm_date - print out the system date and time

SYNOPSIS

       This performs the same operation as the unix 'date' command, but using the Date::Manip module.

	  dm_date [OPTION]... [+FORMAT]

DESCRIPTION

       This displays information about the current system time, or some other time. Options are:

       -h, --help
	   Print online help.

       -d STRING, --date=STRING
	   Display time described by STRING. STRING can be any string which can be parsed by Date::Manip.  Please refer to the Date::Manip::Date
	   documentation for details.

       -f DATEFILE, --file=DATEFILE
	   This reads each line in DATEFILE, and extracts a date from it and prints out the information.

	   Blank lines and lines starting with a pound (#) are ignored. Lines not containing a valid date are also ignored.

       -r FILE, --reference=FILE
	   Displays the last modification time of FILE.

       -R, --rfc-2822
	   Displayc the date and time in RFC 2822 format.

	   Example: Mon, 07 Aug 2006 12:34:56 -0600

       -u, --utc, --universal
	   Converts the date to UT (GMT) and prints out the information.

       Only one of -d, -f, or -r should be included. If more than one is included, the first one from the list (-d, -f, -r) is used and any other
       is ignored.

       The format string starts with a plus (+) and contains any of the format directives described in Date::Manip::Date.

KNOWN BUGS

       None known.

BUGS AND QUESTIONS

       Please refer to the Date::Manip::Problems documentation for information on submitting bug reports or questions to the author.
