This is a relatively old bug. When the program is left running during the night when DST kicks in or out, the change in system time triggers the warning message about all open files having changed.

I don't know what DST is but this also happens to me from time to time.

It's old bug what appears 2 times a year in case your country uses DST (Daylight saving time) and you will let PSPad open when time is changed.
