Android Call log date convertion -

i have call log backup android mobile phone, , i'm trying know date & time of calls.

the log says:

<htccallog> new=1 numbertype=3 duration=28 number=person's phone number type=1 _id=1853 numberlabel=null name=person's name date=1333119990954 

here's problem. when try converto date time (i'm using .net's cssharp), got following date 02/01/0001 01:01:51, of course not valid date of call.

trying convert today's date , time long number utc format, got 130134760479804654 larger number in log file.

could points me i'm doing wrong? following code.

    long datelong = long.parse("1333119793100");     datetime date = new datetime(datelong, datetimekind.utc);      console.writeline(date.tostring("dd/mm/yyyy hh:mm:ss"));      datetime today = datetime.now;     console.writeline("\n\n{0}\n{1}", today.tofiletimeutc(), datelong);      console.readkey(); 

thanks much

sorry, don't know of unix word. googleing little, found 'epoch' time, found out convertion function:

public datetime fromunixtime(long unixtime) {     var epoch = new datetime(1970, 1, 1, 0, 0, 0, datetimekind.utc);     return epoch.addseconds(unixtime); } 

thanks anyway.
