[ncl-talk] "cd_inv_string" question

[Alan Brammer]

That’s my bad.  The counter is only incremented 2 spaces instead of 3.  So in your example it is decoding “-0” as the hours.   I possibly only tested with day as the last number so never picked up on this.  

For your example you could add an extra hyphen (any character but % will do) in the format after %J to bump the counter back into the correct position.  

e.g.
print(cd_calendar(cd_inv_string("1980-001-05", "%Y-%J--%H"), 0))


or edit  $NCARG_ROOT/lib/ncarg/nclscripts/contrib/cd_inv_string.ncl
line 117 should be:
	strm = strm+3



 Apologies all. 



Alan
