[rrd-users] GAUGE rrd storing data as NaN

I am not sure if my timing is off, I've create these before.  I am 
recording the number of transactions in the DB every 5 mins

  rrdtool create /opt/RRD_REPO/site02_trans.rrd -s 300 
DS:TRANS:GAUGE:600:0:U RRA:AVERAGE:0.5:1:24 RRA:MAX:0.5:12:24 
RRA:MAX:0.5:84:7 RRA:MAX:0.5:288:31

When I run the update it gives the following output and then there is 
nothing in the rrd but NaN (not a number)

/usr/bin/rrdtool updatev /opt/RRD_REPO/site02_trans.rrd 1367945701:1556
return_value = 0
[1367945700]RRA[AVERAGE][1]DS[TRANS] = *NaN*

I don't see what I did wrong, except the timestamps differ by about 2
