We are happy to tell you that you just discovered Daylight Savings
Time. For more information see:
http://webexhibits.org/daylightsaving/b.html
Instead of using mktime/date consider using gmmktime and gmdate which do
not suffer from DST.

Dear derick,
Thanks for your prompt reply ... happy that it's not a bug ... but unhappy to change thousands of code line :( 

You can close the ticket :)

No need to change 1000s of lines of code, just tell PHP that you want to use UTC:

date_default_timezone_set( 'UTC' );
