     The shortwave radio time standards (like CHU in Canada) only   
   broafcast "co-ordinated Universal Time" signals (which I believe are   
   "Greenwich Mean Time) and are not location specific and do not handle   
   daylight savings time. Local time and DST must be handled by   
   programming in the recieving device - entered by the operator and not   
   "portable" across time zones. GPS based time is fully portable and can   
   determine if DST is applicable based on date and location - but would   
   still require "updates" if DST was repealed in any geopolitical area.
