please help with mktime/daylight savings

Marcus

Hi all, sorry to post yet another unix timestamp question, but I've been
looking through php.net and google and can't find exactly what i need...
plus I think my brain has shut down from too many hours of php code... :-)

Anyways, here is my problem... I am displaying an HTML table that
represents a person's schedule for the week... I query a database and
take the absolute earliest starting time, absolute latest ending time,
and display a table with all times in between (on predetermined
intervals). For example, say my first column represents Monday... right
now what I am doing to get Tuesday's values is multiplying my mktime(0,
0, 0, $month, $day, $year) value for Monday by 86,400 (the number of
seconds in a day). Everything works perfectly fine, except when I come
across the first Sunday in April and the last Sunday in October...

The April Sunday still works fine, but in October, it displays that
Sunday twice. My question is how do I take into account the difference
in hours as a result of daylight savings time? I know I can use "I" as
the format string in date() to see if the date is during daylight
savings or not, and I tried using this to make it work, but it doesn't
seem to be doing what I want.

Thanks so much in advance for any help you can provide.

don't do :
mktime(0, 0, 0, $month, $day, $year) + 86400

do :
mktime(0, 0, 0, $month, $day+1, $year)
