How to adjust the time by the visitors' timezone

[terryds]

Hi..

How to adjust the time by visitors' timezone ?

I mean, by my timezone (GMT+4), I posted an article at 11:45 A.M.

And, I want my visitor see the time adjusted to his/her timezone.

 

For instance, if a man in GMT+2 see the time, it'll be 09:45 A.M.

 

Thanks in advance

Do you want to assume their computer has the correct local time?

Do you want to assume their computer has the correct local time?

Yes, i do.

 

So, the illustration is below.

I posted an article in my site. The timezone set in the configuration setting is GMT+4 (assume the time is 11:45 A.M.)

Then, I want my site visitors in other timezone see that the time i posted the article is adapted by their timezone ( If the man is in GMT+2 timezone, so he will see that the time i posted the article is 9:45 A.M.)

 

Please tell me how to do that

 

Sorry for my bad English skill

In Php you can use...

$timestamp = 1000*Time(); //milliseconds from Jan 1, 1970

In Javascript you can use...

var timestamp = new Date().getTime(); //milliseconds from Jan 1, 1970

...so perhaps in Javascript you could create a millisecond offset global...

var msec_offset = Math.round(('<?php echo Time(); ?>' - Math.round(new Date().getTime()/1000))/3600)*3600*1000;

...then you could use the fact that Javascript can create a new date from a timestamp...

var date1 = new Date(millisecond_timestamp_from_Php + msec_offset);
