Re: time step adding

There are a lot of 'time/calendar' functions.
Please look at the documentation.
http://www.ncl.ucar.edu/Document/Functions/ [ See "Date" ]

tunits = "hours ref 1-1-1 00:00:0.0" ; use whatever you want

hard wired
tStrt = ut_inv_calendar(2010,1,12,12,0,0,time@units, 0)

use variables
tStrt = ut_inv_calendar(year,month,day,hour,minute,second,units, 0)

print(tStrt)

tstep = 12
ntim = 100
time = tStrt + ispan(0,tstep*(ntim-1),12)
Then you can use

ymdh = ut_inv_calendar(time, 0) ; what ever option you want
