[ncl-talk] Issue with cd_calendar

[Dennis Shea]

Glad issue is fixed:


re:

Variable: time (subsection)

Type: double

Dimensions and sizes: [time | 11]

Coordinates:

            time: [525573024.6776075..525573214.5466383]

Number Of Attributes: 4
...

*  comment : seconds since 2000-01-01 00:00:00.0*

*  units : seconds*


============


It looks like the file has the 'units' and 'comment' attributes mixed.
Kinda confusing, really.


   time at units = time at comment   ; assign correct units
