Ok, right - duh.  Let me back up a couple of steps.

I'm passing a 128 byte char array.  I allocated it to provide enough 
room for the date/time stamp this function is returning.  strlen(tout) 
will resolve to the length of the tout string.

You said above that I shouldn't be using strlen(tout) and instead I 
should be passing 128.  Would I be better off using sizeof(tout) instead?

Also, the code has always worked.  I just recompiled it recently.  Now 
the date works but the time isn't appearing.  What could be causing that?


Thanks!
