Can you write last update time of ecmwf/gfc/...e.t.c under "Fcst model". Sample in here:
And time of next update.
That would be a good idea (if there is enough room for it on phone app)
But personally I would prefer to have there the reference time (or run time 00Z, 06Z, 12Z… of the model), nothing else. I already asked for it sometime ago…
