No. In fact, daylight saving is the most complex matter in date and time 
calculating. I always devoutly assume that the browser keeps track of this, 
and if it doesn't, Too Bad.

As far as I understand getTimezoneOffset should reflect daylight saving 
time, but no doubt some browser will have some bug.

Sorry, I think it would be best to forget about it and hope everything goes 
well.
