[IDV #XHK-934272]: use of time coord in netcdf

Greetings Stu,

I'm not exactly sure when the changed occurred, but you will need to change the 
unit on your time variable from

"Myear"

to

"Myear since 0001-01-01"

It looks like the assumption would be made that a time variable with unit Myear 
was relative to 0001-01-01 0Z, but now a reference date is required as part of 
the unit.

Cheers!

Sean
