Re: BUG: date 7.1 - reading date string

[Klaus Bramstedt]

Dear Sven, Bob, Philip,

thank a lot for your hints! The daylight saving time (DST) is indeed the 
problem, so I have to use the '-u' option of date for proper working of my 
script.
Sorry for bothering, I should have thought myself about this. Maybe an 
additional hint in the error message to the DST problem would help other 
users (like (DST gap))?

thanks again

Klaus
