##### set meteo data

## Most platforms support time zones of the form Etc/GMT+n and Etc/GMT-n (possibly also without prefix Etc/), 
## which assume a fixed offset from UTC (hence no DST). Contrary to some expectations 
## (but consistent with names such as PST8PDT), negative offsets are times ahead of (east of) UTC, 
## positive offsets are times behind (west of) UTC.
