[Radiance-general] Radiance's conventions on locational information

[Christopher Rush]

I think if you specify the time with a time zone designation like GMT, the -m parameter is ignored.
 
> the gensky command is: "gensky 1 1 9:00GMT -a 51.15 -o 0.18 -m 0" or "gensky 1 1 9:00 -a 51.15 -o 0.18 -m 0"

I have always assumed (but would like to confirm and open for discussion), if you give a date that is outside of the daylight savings time period (say January) but give a time of 9:00BST, would it incorrectly apply the 1 hour offset? In other words, the user or script must manually determine for the date in question, if the time should be given on the command line as 9:00GMT or 9:00 BST.
