[ncl-talk] systemfunc("date")

[Joseph Zambon]

Mark,

For your application, the date string for the UNIX command would be...

date +'%Y-%m-%d-T%H:%M:%S'

as in...
jbzambon@:~$ date +'%Y-%m-%d-T%H:%M:%S'
2014-12-01-T11:56:02

As you have been doing, use systemfunc along with that UNIX function to get the desired output...

ncl 6> creation_date =systemfunc("date +'%Y-%m-%d-T%H:%M:%S'") 
ncl 7> print(creation_date)                                     


Variable: creation_date
Type: string
Total Size: 8 bytes
            1 values
Number of Dimensions: 1
Dimensions and sizes:	[1]
Coordinates: 
(0)	2014-12-01-T11:57:35

See the man date page for more info on formatting from the date function.
