Not sure if that will help much; zonenow.tab has a very limited set of timezones, so for many countries, the precondition "if at least one of its timezones appear in zonenow.tab" will not be met. For example in the case of Spain (the example in my original email), I have three zones: - Europe/Madrid - Atlantic/Canary - Africa/Ceuta But none of them appears in zonenow.tab. Same with many European countries (I am mentioning European countries just because these are the ones I am more familiar with, there's nothing specific about Europe here) BR, Guillermo Rodriguez Garcia [email protected]
