Try looking at the man page for your implementation of the date command.
On a Linux system, you can get (for example) the number of seconds from the epoch like this:
Or if you want the date yesterday in YYYYMMDD format, you can do this: Note: the --date option is specific to GNU date, as far as I know, and is not portable...
If you have any other questions about date handling, please respond, as I have been doing a lot of tedious date juggling in scripts lately.
If you do reply, please include your operating system (available via the uname -a command), and if possible, which "date" you are using. Also, please give examples of which formats you are converting from, and the expected output.

tmpwatch
TMPWATCH(8) System Administrator's Manual TMPWATCH(8)NAME
tmpwatch - removes files which haven't been accessed for a period of time
SYNOPSIS
tmpwatch [-u|-m|-c] [-faqstv] [--verbose] [--force] [--all] [--test]
[--fuser ] [--atime|--mtime|--ctime] [--quiet] <hours> <dirs>
DESCRIPTION
tmpwatch recursively removes files which haven't been accessed for a given number of hours. Normally, it's used to clean up directories
which are used for temporary holding space such as /tmp.
When changing directories, tmpwatch is very sensitive to possible race conditions and will exit with an error if one is detected. It does
not follow symbolic links in the directories it's cleaning (even if a symbolic link is given as its argument), will not switch filesystems,
and only removes empty directories and regular files.
By default, tmpwatch dates files by their atime (access time), not their mtime (modification time). If files aren't being removed when ls
-l implies they should be, use ls -u to examine their atime to see if that explains the problem.
If the --atime, --ctime or --mtime options are used in combination, the decision about deleting a file will be based on the maximum of this
times.
The hours parameter defines the threshold for removing files. If the file has not been accessed for hours hours, the file is removed. Fol-
lowing this, one or more directories may be given for tmpwatch to clean up.
OPTIONS -u, --atime
Make the decision about deleting a file based on the file's atime (access time). This is the default.
-m, --mtime
Make the decision about deleting a file based on the file's mtime (modification time) instead of the atime.
-c, --ctime
Make the decision about deleting a file based on the file's ctime (inode change time) instead of the atime; for directories, make
the decision based on the mtime.
-a, --all
Remove all file types, not just regular files and directories.
-d, --nodirs
Do not attempt to remove directories, even if they are empty.
-f, --force
Remove files even if root doesn't have write access (akin to rm -f).
-t, --test
Doesn't remove files, but goes through the motions of removing them. This implies -v.
-s, --fuser
Attempt to use the "fuser" command to see if a file is already open before removing it. Not enabled by default. Does help in some
circumstances, but not all. Dependent on fuser being installed in /sbin.
-v, --verbose
Print a verbose display. Two levels of verboseness are available -- use this option twice to get the most verbose output.
SEE ALSO cron(1), ls(1), rm(1), fuser(1)WARNINGS
GNU-style long options are not supported on HP-UX.
