Gwillim Law scripsit:
If anyone is not satisfied with ISO 8601, they must want to convey more information than just the offset from UTC. What useful information is imparted by EST (or CDT), that isn't imparted by -05:00?
In particular, if we are going to talk about future times (including recurring times), we really need to represent the entire tz name. For example, my employer is currently publishing news articles at 1705 EST and others at 2000 EST. But we do not state our publication dates in EST, nor in GMT, but in "New York time", because we will always be publishing relative to America/New_York, no matter how much that changes. Currently, New York time is -05:00, but it regularly changes to -04:00 in (boreal) summer, and in principle it could change to some other offset altogether. -- John Cowan cowan@ccil.org One art/there is/no less/no more/All things/to do/with sparks/galore --Douglas Hofstadter
