Time zone conversion

[Switto]

Hi Again,

I am working on a list that is coming from SharePoint and has 4 different date and time columns.

It has different time zones like below.

Fri Dec 03 2021 13:56:07 GMT+0800 (China Standard Time)

Mon Nov 22 2021 04:49:13 GMT-0500 (Eastern Standard Time)

Fri Nov 19 2021 13:08:01 GMT+0100 (Central European Standard Time)

Fri Nov 12 2021 15:46:18 GMT+0530 (India Standard Time)

Fri Oct 29 2021 12:35:15 GMT+0200 (Central European Summer Time)

Now I would like to change all this time zones to GMT+0530 (India Standard Time).

Is it possible to change it as per google search, I got result of people converting column of a particular Time zone not a mix of time zones.

Thanks in Advance
