Ok. I thought I gave examples of time changes not intentionally made by the user. The weekly internet time synch where you can't define the scheduled time, or computers going into sleep/hibernation mode.
Nice try, but no cigar :-)
I am sure that, if we really wanted to, we could come up with a hundred ways that a change in system time could affect normal applications.
The change made in the recent beta focused on improving older features, that unncecessarily used system time to measure time, so that they used tick counts to measure time, like most features in mIRC. That's it.
