Do me a favor and delete /sdcard/TWRP/.twrps and reboot recovery for another check if you don't mind...
No go. Tried two different times, same result. See the screen capture of the folder. I can't attach the log file as I'm getting an error. I'll have to upload it someplace if you want it. You can see the fix date results there as well..
[ EDIT 1 ] Okay, you can grab the log from
here. I'll delete it in a few days.
[ EDIT 2 ] Are my tests the only ones generating the funky dates? Hmm..
[ EDIT 3 ] Last edit, really!

I flashed the previous version which did not seem to have any issues with the .twrp file created by your version, suggesting they may be the same. Did a quick backup and the date/time was correct except for the year, of course.
