Question on datenum

Hi,

I am trying to create an hourly timeseries for a tidal record but am having some trouble with datenum functions. The example of the code i used is written below:

time=datenum(2006,8,31,10,15,0);
time=(time-datenum(2006,8,1,0,0,0));
t = 0:1:max(time);
eta3 = amp*cos(((((2*pi)/24))*t)+pha);

figure;
plot(t,eta3,'.-')
datetick('x',0)

Using, the datenum function, i wanted to create an hourly time period but instead i have created a daily time period. Any suggestions to correct the mistake abouve is greatly appreaciated.
