[ncarg-talk] convert the time "since seconds" to month-year

[Amal Inge]

Dear NCL experts,

I want to plot a time series of monthly data of nc file with the script
attached but it didn't work, i think that I should convert the time "since
seconds" to month-year.
how could i do this please?

many thanks
Amal
