note 102034 added to function.strtotime

I am using this code if ($values["Cat1"]) $values["TargetTime"] = date("Y-m-d H:i:s",strtotime("+2 hour")); if ($values["Cat2"]) $values["TargetTime"] = date("Y-m-d H:i:s",strtotime("+4 hour")); if ($values["Cat3"]) $values["TargetTime"] = date("Y-m-d H:i:s",strtotime("+1 day")); if ($values["Cat4"]) $values["TargetTime"] = date("Y-m-d H:i:s",strtotime("+2 day")); if ($values["Cat5"]) $values["TargetTime"] = date("Y-m-d H:i:s",strtotime("+3 day")); But were I am using +1 day, +2 day and +3 day, that is OK, My problems are +2 hour and +4 hour. As our business hours are only 08:00 until 16:30, if I select a Cat2 at 16:00 it puts the TargetTime at 20:00 on the same day and not 11:30 the next day. Any ideas on how I can make the strtotime only operate between 08:00 and 16:30?
