I think your description of 1198990800 is a little off
sqlite> select datetime(1198990800, 'unixepoch');
2007-12-30 05:00:00
To "truncate the hour", as you say:
sqlite> select strftime('%s', date(1198990800, 'unixepoch'));
1198972800
Which translates to 2007-12-30 00:00:00

Hi P
Sorry for the confusion!
Current my hourAppAcclTable is store the following
1, 1198990800
2, 1198998000
which is 2007-12-29 21:00:00 and 2007-12-29 23:00:00 if I used the
datetime function to show the time format.
What I want is to store this time stamp in different table but truncate
all the hour fraction, dayAppAcclTable
1, 1198915200
2, 1198915200
which is 2007-12-29 00:00:00 which GUI run the datetime function
Thanks a lot,
Joanne

I am not really sure what you want to do, nor can I figure out what
exactly you have tried to do. Did you try
sqlite> select date(1198990800, 'unixepoch', '-8 hours');
2007-12-29
is that what you want when you mean "truncate the hour"?
Please read the datetime wiki at
http://www.sqlite.org/cvstrac/wiki?p=DateAndTimeFunctions carefully.
Most of your questions will be answered there.
