​todays_date = systemfunc("date")
​todays_date = systemfunc("date '+DATE: %Y-%m-%d')

Type "man date" on the UNIX prompt to see other date formats you can use.
There are quite a few.

​You can use gsn_add_text, gsn_text, or gsn_text_ndc to add or draw any
text string as an annotation to an existing plot. See our text examples
page for several ways to add text strings:

You can also check out the "infoTimeStamp" procedure:
