snapshot-timemachine file timestamp notes (from zfs-snap-diff#13) #1

from j-keck/zfs-snap-diff#13:

Hi,

It seems I failed to notice two things with the original code with #12. Appologies.

the timestamp given for the record is the snapshot timestamp; is it possible to use the file timestamp instead? Also; parse-time-string would be happier with a RFC 822 datetime:

"Parse the time in STRING into (SEC MIN HOUR DAY MON YEAR DOW DST TZ). STRING should be something resembling an RFC 822 (or later) date-time, e.g., "Fri, 25 Mar 2016 16:24:56 +0100", but this function is somewhat liberal in what format it accepts, and will attempt to return a "likely" value even for somewhat malformed strings. The values returned are identical to those of `decode-time', but any unknown values other than DST are returned as nil, and an unknown DST value is returned as -1."
