[gradsusr] Monthly mean from 16-days interval data for one year

[Rafanoharana Serge Claudio]

Hi all,

I found the problem related to the time and I just want to share here in
case you face the same problem.
Do not use or create a variable which starts from 0, for example 01 or 001
or anything else especially for the variable time. Just start directly with
1, 2, ... It was the cause of my problem.

Regards

Serge
