[wp-hackers] Possible bug in the function human_time_diff()

[Otto]

No, that doesn't make any sense unless you set your time zone wrong to
start with.

Look at your code:
<?php echo human_time_diff(get_the_time('U'),
current_time('timestamp')) . ' ago'; ?>

get_the_time('U') gets the timestamp of the post, as WordPress thinks
it is. So it's accounting for the time zone setting there, or, at
least, the time zone that the blog was set to when the post was made.

current_time('timestamp') gets the time with time zone setting accounted for.

human_time_diff doesn't care about time zones. It's taking two
absolute times and getting their difference.

On the settings page, your time zone should be YOUR time. The "server
time" should always be the absolute UTC/GMT time, regardless of what
time zone it's in. The important point here is that after you've set a
time zone on the settings screen, then it will show you your local
time, where you happen to be sitting at. Where the server is located
is irrelevant.
