Get forecast time from GFS gribfiles

Hello,

I am using NCL to create plots from the GFS grib files. Now I am
trying to display a label with the current forecast time on the map. I
have already positioned my text label with gsn_text_ndc, but I could
not find a method to get the current forecast time. Which variable do
I have to use for this?

grib_file=filename
fin = addfile(grib_file,"r")
lat2d = fin->gridlat_0
lon2d = fin->gridlon_0
wind_u = fin->UGRD_P0_L103_GLC0(:,:)
wind_v = fin->VGRD_P0_L103_GLC0(:,:)

Thank you for your help!

Best regards,

Jonas Kaufmann
