Hendrik Lipka / TimeZone

This library takes the current time (which must be set to UTC, e.g. via an NTP call), and applies a timezone definition (loaded at startup) to calculate the local time. This includes the handling of daylight saving. See http://mbed.org/users/hlipka/notebook/time-zone-handling/ for more information (esp. how to get a time zone definition file).
