Timestamp method generates Invalid timestamp

Hello,

Been using the "timestamp" method for a long time, but it has stopped working.

I'm now getting this error : Invalid timestamp: Invalid date/timestamp : "2026-09-31 05:43:41,410". My guess is that the ",410" part is unexpected here.

I used this method recently with no issue, but I'm not sure on what version I was. I use it via the command line, so I don't get update notices. I did update to 4.27 and the issue is still there.

There were recent Windows updates, so something may have change there that impacts Advanced Renamer...
