I am not sure if this is hard question or not, but I cannot figure out what is the best way or approach for this case.
I want to synchronize the time of my admin account of the system I am working now, to see the client time base on their time zone. And I has to be ALL the times. for instance I have an admin time of 1:20am in America/New_York time zone, and I will be viewing my client depending on their time zone, like 'Asia/Singapore' will be 1:20pm.
So 1:20am for admin, but admin viewing client will be 1:20pm.
What is the best way to convert those time depending on time zones, and sync it to client depending on client`s time zone.
I have sorted this out by making my function to convert it to client, BUT I will have to use that function to every datetime of my database.
What is the best way to do that?
