How to convert AD accountexpires in Local timezone format

Hello Everyone,

In my current project IDM 7.2 SP10, we are reading accountexpires attribute from AD and then converting it to a readable format using uInt8ToDate function.

This function is converting the date in readable GMT format while client want it in local time. While searching SCN, I got below post which says that "True" switch is not working in uInt8ToDate function and even I observed the same.

Can anyone guide how can I convert the date in local timezone. I tried to use getTimezoneOffset() but it thrown error. Any help with the JavaScript formula will be appreciated.
