Re: [sqlite] How to truncate the hour fraction
sqlite> select datetime('1201561222', 'unixepoch');

OK, so now it's clear your values are Unix times.
sqlite> select strftime('%s', date('1201561222', 'unixepoch'));
1201478400
Effectively strips the time portion of your time value
sqlite> select datetime('1201478400', 'unixepoch');
2008-01-28 00:00:00
Proves the result is what you asked for.
Good luck!

So you just want the date (i.e. No time at all)? Seems like you have
two options. You can mod against 86400 (number of seconds in a day),
or you can just use the date(DateField) option, to only output the date.
sqlite> SELECT date('2007-01-19 12:54:32');
2007-01-19
sqlite> SELECT date('120159','unixepoch','localtime');
2008-01-28
Lots of good docs here:
