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
