Upstream changes:
1.1 2020-09-19

Added fix for errors decoding registry timestamps. (This was due to the
interpretation of dates in timegm changing in recent versions of Perl.)
Thanks to B.M.W. and Slaven Rezic for their help with this.

Updated as_regedit_export to handle undefined REG_SZ values.
