OK, i'm having trouble with a query that I hope someone can help me with...

I have a table that stores signup dates in unix timestamp format and I'm having problems trying to output data in this way:

date | signups
02-01-2008 | 5
02-02-2008 | 50
02-03-2008 | 10
02-04-2008 | 20
02-05-2008 | 25


SELECT sup_date, COUNT(id) FROM users WHERE sup_date > "1199145600" AND sup_date < "1202774400" GROUP BY sup_date

is there a way to convert the timestamps to output dates???

my goal is to be able to query the amount of signups for each day for the past 30 days - maybe i'm going about it wrong..
