An admin on our site somehow accidentely deleted a couple of ours mods' accounts through the ACP, I'm just trying to fix their join dates on their new accounts (already assigned the posts to the new accounts etc.)

I know how to change the join date, but not what I need to change it to. 

This is one of our member's join dates

What would I need to type in to make the join date Feb. 10? I can't seem to make a connection between those numbers and the actual join date.

 

If anyone could help that'd be great.

Those numbers are timestamps, you can use this site - http://www.unixtimestamp.com/ - to convert dates to timestamps. 10th February 2015 for example would be 1423526400
