Here's what I found just playing around with [clock scan [clock format]].



Running various numbers through I maxed out at

clock scan [clock format 3093528009599]



If, however, I put in 3093528009600 I get

unable to convert date-time string "Sat Jan 01 00:00:00 PST 100000"



I then ran clock format 3093528009599 by itself and get the date-time string above 01/01/100
000 @ 00:00:00.

So it looks like some clock options don't take the same data width as others.



BTW, I'm running Tcl 8.5.7.

It is possible.



This looks like the Y2038 problem you get with 32bit clock values, overflowing

the range for such integers.



IIRC in Tcl 8.5 the clock values can become wideint, i.e. 64bit, preventing the

overflow.
