It can the date and time in single string output format to be used as environment variables which will then be used in scripts or as command line arguments to programs using date/time items.

It can also create the date and time in single string format to be sent to programs for use in determining current date.

Operation

With options, you can print this months calendar with a heading.

However, the program is designed to produce a more elaborate output of combinations of todays, month, day, year, and various time and julian date information.

The power of the program comes from its ability to produce an output that can be redirected to a file which will them be used to generate various information in the form of environment variables relating to the month, day, year, etc, information. These environment variables can be used to set file or folder names, and other information which may be useful in unnatended scripts.

The options allow the output of the following:

Numeric values for the following:
Other variations

These items which are output to the screen can be used in scripts to generate environment variables which will later be used create filenames and folder names relating to a particula date and time. This is useful when using in an upcopy script to creats pseudo backup files.

--[literal]  use the minusminus to insert a literal. If spaces are to be inserted, quote the item. If fact, you can't go wrong always quoting.

Options can be combined to form contiguous string output

-mdyHMS   gets something like: 02032008230101

Special delimeters are recognized (colon :, dash -, slash /) are recognized as seperators for the mdy, HMS items, and can be directly embedded.
ie. -m:d:y --"spaces" -H-M-S will yield: 02:03:2008     23:10:59

if only format of: mm dd yyyy on command line by itself, then that date is converted to julian date, and displayed
C:>dater 2 2 2008 results in: 02/02/2008=2008033
