Where would I find that utility?

That said, the os9's day 1 year 1 is 1969 or1970. Its been so long I've 
forgotten but thats the start of time in the *nix world", so its good 
till 2038 before it runs out of seconds and rolls over due to the size 
of the var that holds the the time. Because the year in the dp 
reservation is a byte, we've had to play tricks between the time stored 
in those 6 reserved bytes to get the proper date for display and file 
dating. All this was before y2k, so I'm 18 years rusty. But if that code 
preferably in src form can be located, I might see if I can fix it. 

Warranty void of course. :)
