Timezone Adjustment Hack · **Released**: 03-23-2003

This is kinda hard to explain, but this hack basically detects when a user doesn't have their timezone set correctly (when their set time doesn't match their computer time). It gives the user a JavaScript prompt asking whether they would like to update their timezone. If they click "OK", it pops open a small window for a couple of seconds, updates the user's timezone offset accordingly in the database, and closes the window.

This is a beta!! I've played with it a little, and it appears to work *most of the time*. I'm releasing it in the hopes that someone can help me fix any errors that come up. (I expect errors to come up.)

It is important to note that the idea was inspired by FireFly's HiveMail, but the JavaScript is written completely by me. I previously asked about it (underestimating my own abilities, I guess) and was told that I had to get permission from Chen. I emailed him but haven't received a response, so I went ahead and wrote this. If any mods have a problem with this, just delete the thread and the hack.

This hack does not work for users in Newfoundland, since their offset is -3:30.

IF YOU DOWNLOADED THIS BEFORE 5:45 PM PDT ON 03/24/03, change all instances of "hi_timezoneoffset" to "hi_timezone" (disregard the quotes in both cases). Then, re-apply step 1.

IF YOU DOWNLOADED BEFORE 6:10 PM PDT ON 03/24/03, remove from your hi_timezone template the following:

Code:

	} else if (difference<0) {
		sdifference="-"+difference;

IF YOU DOWNLOADED BEFORE 7:35 PM PDT ON 3/28/03,
open global.php and replace:

Code:

  eval("\$timezonecheck = \"".gettemplate('hi_timezone')."\";");

with:

Code:

  $nowhours=vbdate("H",time());
  eval("\$timezonecheck = \"".gettemplate('hi_timezone')."\";");

Instructions are attached. Don't forget to upload updatezone.php as well! Enjoy!

Very cool idea, Nick.

I was going to look into this when I had time, glad to see that you've done it. I'll have a look.

I see what you've done - clever - if you're making it so that it checks on the index.php file, it might be a good idea to add the hi_timezoneoffset template into the templateused cache in index.php OR instead of using templates, just add the contents of hi_timezoneoffset in the <head> section of forumhome. Otherwise, it's an extra unnecessary query in forumhome.

Also, you can achieve the same thing by using templates - instead of editing global.php, add the same code to phpinclude (including the contents of the PHP file - this whole hack could be template based).

Great idea. I'm at work, but when I get home I'll play around with it.

Hmm.. Nice hack, N!ck. I'll look into installing this once it's out of Beta stage, expecially since it runs off of index.php.

N!ck · #6 03-24-2003, 12:04 PM

Erwin, you're right! I forgot about adding it to the $templatesused variable. Thanks for reminding me; I'll update the instructions.

It's not working for me. Something looks odd though. You've named a template hi_timezoneoffset yet in global.php you point to hi_timezone. Changing it to hi_timezoneoffset didn't help though.

N!ck · #10 03-24-2003, 10:52 PM

No, change everything from hi_timezoneoffset to hi_timezone. Sorry for the mistake. Fixed.

Has anyone tested this extensively?
