can you explain this a bit?
Do you mean when you change the time on your machine?
And do you mean that you want the browser to return some other date and time?
i want to pin date and time to this timezone UTC +20:00 Cairo, when user change time on machine, need to make the sync from pin something not from the local machine
The only way I know how (sorry I am not experienced with this topic) is to get the date and time from a server that is already in the required time zone. (Because otherwise you only have the local time and date on the person’s client machine)
