Reference Time of the Forecast

[idefix37]

Hello,
Could it be possible to show the reference hour and date for each model run. It should be nice to have this information on the right panel, below ECMWF, GFS, NEMS. I know that it is difficult to find space for this. Sometime during the day, there is 12h difference between some model runs. It is possible to obtain this information when we compare the 3 model forecasts for one location. But it's long to do it.
By the way, why resolution of GFS is 22km and sometime 13km?
At the end what are the figures shown on the map near a square dot like 123ms or 94ms?
