David Smart / TimeInterface

A time interface class. This class replicates the normal time functions, but goes a couple of steps further. mbed library 82 and prior has a defective gmtime function. Also, this class enables access to setting the time, and adjusting the accuracy of the RTC.

Dependencies:   CalendarPage

Dependents:   CI-data-logger-server WattEye X10Svr SSDP_Server
