Netcdf averages time varable when averaging multiple .nc files

I have averaged a bunch of hourly netCDF files (for one year) to create one large netCDF file that contains an average daily value. The time variable represents hours since 2005-1-1 00:00:00 and looks like this:

time = 11.5, 35.5, 59.5, 83.5, 107.5, 131.5, 155.5, 179.5, 203.5, 227.5...;

However, I would like the time variable to represent the beginning of the day so that it looks like this:

time = 0, 24, 48...;

Is there a way to manipulate the time variable so that it represents the beginning of the day instead of the middle of the day?

Thanks!

you could also use cdo to shift the time axis

cdo shifttime,-11.5hours infile.nc outfile.nc

It seems as if this command may have solved my issue:

ncap2 -s "time=time-11.5" infile.nc -o outfile.nc
