Timestamps in Archive Filenames

Hey there,

as of now timestamps for archive filenames are kinda weirdly formatted without padding zero on single digit occurences like this:
m-d-yyyy-h-M-S

This is on one side hard to parse for external scripts or programs and also shows files listed by filename "out of order" (e.g. for incremental backups).

Would it be possible to add the option to change timestamps to a fixed width timestamp and something that sorts properly when listing files by name (like this maybe: YYYYmmdd-hhMMSS) OR maybe even supporting ISO8601 timestamps?

Thanks for taking the time to read this. Cheers and thanks for that awesome program!
