I hope this topic is appropriate

I'd like to be able to use the return value of a Date object's getTime method for the id of setInterval. I think currently it may cause an overflow -- at least that's the sort of message I'm getting via Script Debugger.
Would this be an easy / worthwhile change to setInterval in fscript.dll?
I'm currently using version 1.20 -- at least that's what the file's properties indicate.
Thanks for the consideration -- and below is a quote from MDC's documentation on Date objects:
getTime
Returns the numeric value of the specified date as the number of milliseconds since January 1, 1970, 00:00:00 UTC (negative for prior times).
