I've found how to display sunrise and sunset at a given location, but can't find out how to get php to automatically allow for summer time here in Europe ?. This happened today - but I know the USA did it early this year - so can you preset the date to do it ?. echo ', sunrise time : ' .date_sunrise(time(), SUNFUNCS_RET_STRING, 55.000, -3.000, 90, 1); I know I can manually change the last figure to add 1 hour to GMT - but can php be used to do it automatically please Malcolm -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
