I'm not sure if this is a osticket issue or Operating System issue but I have found the issue and how to band aid it.When the Time zone date and format settings are set to advanced, but nothing is changed like the photo belowThis is the outcome when trying to pick a date on a custom form with date and time selectorThe solution is to change the Time zone date and format to locale defaults
@B14CK_H4WKAre you using IIS by chance? You should be using the format "MM/d/y" instead of "MM/dd/y" in order for the day not to duplicate itself. See PHP's date format documentation here.Cheers.
@KevinTheJedi No I am using ubuntu server with Plesk Panel installed on it. I could try "MM/d/y" and see what happens but ironically "MM/dd/y" is the default setting once you chose advanced.
