Perl - Extract 12 hour time, convert to 24 and subtract 15 minutes?
OK, I am by no means a programmer...
I have been given the task to do some automation scripts. I have got most of it working from snippets I have found on the Web.
One requirement has me stumped.
The initial timing file created by the user is a comma delimited in the following format.
Task,Room,Start,End,Date
What I need to do is open the file, pull the Start which is in 12Hour time, convert to 24Hour time and create a cron entry based on this.
Also subtract 15 minutes from the above time and create another cron entry (to kick off a warning that something is about to happen).
Then do the same for the End.
Is there a simple way to do this other than a big lookup table?

dh_usrlocal
DH_USRLOCAL(1) Debhelper DH_USRLOCAL(1)
NAME
dh_usrlocal - migrate usr/local directories to maintainer scripts
SYNOPSIS
dh_usrlocal [debhelperoptions] [-n]
DESCRIPTION
dh_usrlocal is a debhelper program that can be used for building packages that will provide a subdirectory in /usr/local when installed.
It finds subdirectories of usr/local in the package build directory, and removes them, replacing them with maintainer script snippets
(unless -n is used) to create the directories at install time, and remove them when the package is removed, in a manner compliant with
Debian policy. These snippets are inserted into the maintainer scripts by dh_installdeb. See dh_installdeb(1) for an explanation of
debhelper maintainer script snippets.
When the Rules-Requires-Root field is not (effectively) binary-targets, the directories in /usr/local will have ownership root:staff and
the mode will be 02775. These values have been chosen to comply with the recommendations of the Debian policy for directories in
/usr/local.
When Rules-Requires-Root has an effective value of binary-targets, the owners, groups and permissions will be preserved with one exception.
If the directory is owned by root:root, then ownership will be reset to root:staff and mode will be reset to 02775. This is useful, since
that is the group and mode policy recommends for directories in /usr/local.
OPTIONS
-n, --no-scripts
Do not modify postinst/prerm scripts.
NOTES
Note that this command is not idempotent. dh_prep(1) should be called between invocations of this command. Otherwise, it may cause multiple
instances of the same text to be added to maintainer scripts.
CONFORMS TO
Debian policy, version 2.2
SEE ALSO
debhelper(7)
This program is a part of debhelper.
