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!

How
to
truncate
the
hour
fraction
Thank
Ken,
But
this
is
not
what
I
want.
I
would
like
to
truncate
the
hour.
So
t1:
201561222
->
2008-01-28
15:00:22
and
I
want
t2
?
->
2008-01-28
00:00:00
So
I
want
to
find
out
t2?
which
has
no
hour
number.
Thanks
JP

How

assuming
your
time
is
in
seconds.
try
t1:
201561222
->
2008-01-28
15:00:22
and
you
want
t2:
1201561200
->
2008-01-28
15:00:00
t1
=
t2
-
(t2
mod
3600)

I
want
to
aggregate
the
data
from
hour
table
and
store
them
in
weekly
table
and
startTime
should
not
have
any
hour

Is
there
any

to
truncate
all
the
hour
fraction.
Thanks,
