<p>Indri,</p>
<p>What you want to do can be easily done in python once you've
installed the python-netcdf module
(<a class="moz-txt-link-freetext"
href="https://pypi.org/project/netCDF4/";>https://pypi.org/project/netCDF4/</a>),
as follows:</p>
<p><tt>with Dataset('file_name.nc', 'a') as fid:<br>
fid.START_DATE = '2000-01-01_00:10:00' # or whatever date
you want<br>
fid.SIMULATION_START_DATE = </tt><tt>'2000-01-01_00:10:00'</tt><tt>
# or whatever date you want</tt></p>
<p>-Sourish<br>

The attributes that you highlighted are simple text
strings, which are easy to change. This can be done
on the unix command line with no programming, with
freeware packages such as <b>NCO</b> (NetCDF
Operators). There are several examples in the
description of the <b>ncatted</b> utility (attribute
editor) in the <b>NCO</b> documentation:</div>

</div>
<div dir="ltr"><br>
</div>
<div>Here is an example that might work on your actual
data file:</div>
<div><br>
</div>
<div>ncatted -h -a
START_DATE,global,o,c,'2099-01-01_18:00:00' \<br>
-a
SIMULATION_START_DATE,global,o,c,'2099-01-01_18:00:00'

<div>I am sure there is also an easy way to do this in
python. Perhaps one of the python programmers here
can give an example.</div>

<div>Indri, there is more than one way to
store date and time in a netcdf file.
Please show an actual short example, and
describe the general nature of how you
want to change it. Also, what programming
languages do you like to use for data
work?</div>
