bug#13938: Bug: date(1) -d "relative-to-skipped-time" problem (also in touch(1) -d)

[Aleš Kantor]

Set date to Mar 10, 2013  (the day clocks moved fwd)

This command
    date -d 2:30am
gives "Invalid date," probably reasonable, since that time didn't exist.

This one should work, but fails as well:
  date  -d "2:00am yesterday"
date: invalid date `2:00am yesterday'

Any _relative_ reference to the missing chunk of time will produce an error.
