(2015-07-24, 02:37 PM)Destroy666 Wrote: [ -> ]MyBB provides relative time up to 12 hours, actually: https://github.com/mybb/mybb/blob/featur...s.php#L431 To increase it to 24 the last number in the conditional needs to be 86400.
You'd also have to edit inc/functions.php and add support for any other relative time measures (days, weeks, months, years..) here: https://github.com/mybb/mybb/blob/featur...s.php#L453 How? SImilarly to the 2 conditionals above but with other time stamps and language strings.
I was able to change it to 24 hours but I'm still learning so I'm not really sure how I'm supposed to the remaining formats to change to the ones I mentioned in OP. Could you please help to to change it. Thanks in advance
