I have created a rrd file and updated three entries. But after the update,
rrdtool dump generated the wrong data (the time is not correct, nor the

Here is what I did:
/bin/rrdtool create active_users_wkly.rrd --start  1140480001 --step 604800
DS:active_users:GAUGE:1209600:U:U \

/bin/rrdtool update active_users_wkly.rrd 1141084801:107717
/bin/rrdtool update active_users_wkly.rrd 1141689601:123038
/bin/rrdtool update active_users_wkly.rrd 1142294401:144376

The data I entered is: 
MON 27-Feb-2006 : 107717
MON 06-Mar-2006 : 123038
MON 13-Mar-2006 : 144376

But, the rrdtool dump shows the wrong time, which is starting on Wed. Feb 22
(note that my data starts on Mon Feb 27) and the wrong data (only the first
data is correct). Here is the result from rrdtool dump:
<!-- 2006-02-22 16:00:00 PST / 1140652800 --> <row><v> 1.0771700000e+05
<!-- 2006-03-01 16:00:00 PST / 1141257600 --> <row><v> 1.1209440324e+05
<!-- 2006-03-08 16:00:00 PST / 1141862400 --> <row><v> 1.2913453615e+05

I wonder what;s wrong.
