-RT

Introduction

The reference time is usually the analysis time or the time of the start of the forecast (forecast time=0). However, the grib standard also allows the reference time to be verifying time of the forecast or the observation time as indicated by Grib Table 1.2. While legal grib, you should think twice before setting the reference time to the verifying time of the forecast. The -RT option prints the type (signficance) of the reference time (Grib Table 1.2).
