Re: Beware! Time assignment ...



Wolfgang,
You're right! A listing with V 5.33 gives the same times as V 4.91, but I just checked and V 5.4 gives identical times to V 5.22.
Actually, the real question though is what convention the creators of the files used, and what they intended the start time of the files to be. Some files are obvious, but if you don't think to check that the beginning time of a file is what you expect (you want data from the middle), you could be several days off. Lynn

Dear Lynn

I m not sure this would help, but we still have the reverse problem using
ferret verion 5.22 and 5.33. While we are comparing ncep temperature
fields we will find a 2day lag between these two version. For ex. 5.22 starts at
1.3. while 5.33 starts at 3.3. So what will happen if you are using version 5.33.

Anyway you're right, time axis in ncep data staring 1.1.1.0000 . and changing
the default calendre is changing the starting time.
