Comments in Your Timezone!

Want to change that pesky GMT timezone on your comments page?

  1. Apply the Customising the layout of your Comment Headers tutorial.


  2. Find the line which reads:
    function EntryPage::print_comment(Comment comment) {


  3. On the line beneath it, paste the following, configuring as you see fit:

  4. Find the line which reads: <td colspan="2" align="left" style="white-space: nowrap"><strong>$date</strong> """; print $comment.time->date_format("long")+" - "+$comment.time->time_format(); """</td> and replace it with the following: <td colspan="2" align="left" style="white-space: nowrap"><strong>$date</strong> $tz_date - $tz_time</td>.


This code hasn't been fully tested for all sorts of things like leap-years and such, so if you notice any odd dates, please tell me!
