The SPA100 Provisioning Guide contains a chart of valid Time_Zone values for some timezones (https://supportforums.cisco.com/docs/DOC-26259), but there is no specification of what the values mean. The default value is "-08 1 1". The first number is obviously the offset from UTC. The second two numbers must specify when summer time starts and stops, but how exactly is that specified?
I'm trying to figure out a way of converting from the Daylight_Saving_Time_Rule parameter used on the older SPA devices, into a valid Time_Zone.
