i want store in sqlite database timeintervalsince1970. if use code:

let dateformatter = nsdateformatter() dateformatter.dateformat = "dd-mm-yyyy hh:mm" dateformatter.timezone = nstimezone.localtimezone() var initdate: nsdate = dateformatter.datefromstring("23-03-2015 00:00")! let timeinseconds = initdate.timeintervalsince1970 // 1,427,324,400.0 

when pass timeinseconds nsdate:

let datestore: nsdate = nsdate(timeintervalsince1970: timeinseconds) 

if print datestore:

println(datestore) 

output '2015-03-22 23:00:00 +0000'

timeinseconds = 1427324400.0 -> '2015-03-22 23:00:00 +0000', store '2015-03-23 00:00:00 +0000' interval should 1427328000.0
