>Description:
for date manipulations in ascii form is documented, that all formattings
of date (resp. strftime) can be read by strptime. However, the "%s" 
format (seconds UTC since epoch) is not recognized. A patch, which
integrates this format is supplied.

>How-To-Repeat:
date -j -f "%s" `date "+%s"`

>Fix:
