Thanks for reply Dr. Arindam, I tried as follow:
.......
yyyy = data1(:,0)+2000;
mm = data1(:,1);
dd = data1(:,2);
hh = data1(:,3);
minute = fspan(0,0, 744)
second = fspan(0,0, 744)
data=data1(:,4:1203)
time=new(dimsizes(yyyy),double)
time_at_units = "days since 1800-01-01 00:00:00"
do i=0,dimsizes(yyyy)-1
time(i)=cd_inv_calendar(yyyy(i), mm(i),dd(i),hh(i),minute(i),second(i),time_at_units, 0)
end do
data&time=time
.......................
However, I got the following error: Argument type
mismatch on argument (0) of (cd_inv_calendar)
Thanks again for help,
Joeky

hi Juki,
use cd_inv_calendar() to do that.
time=new(dimsizes(yyyy),double)
do i=0,dimsizes(yyyy)-1
time(i)=cd_inv_calendar(....)
end do
data&time=time
...
