Convert unix time to 12:00 AM of that same day

2011-03-01 Thread Bryan Cantwell
I'd asked before how to convert a unix timestamp to the hour that it is in (and got the perfect answer) : 1298999201 = 3/1/2011 11:06:41 AM (1298999201 - (1298999201 % 3600)) = 3/1/2011 11:00:00 AM Now getting the timestamp converted to midnight of that same day isn't as simple as: 1298999201
