SCCS - A slight scripting issue

I used %H%M for hours and minutes within a date variable, to latch the date/time onto the end of a file, the script it was in is now under SCCS control and the %H% is a predefined parameter for SCCS, so it tags a date with a "/" character in it.

Is there a way to tell SCCS to ignore anything like this within the script body? I know I can get around it by changing the date format, but my users want the old way to work.

Thanks in Advance.
