NTPClient 3.1.0 - 2016.05.31
* Added functions for changing the timeOffset and updateInterval later. Thanks @SirUli
NTPClient 3.0.0 - 2016.04.19
* Constructors now require UDP instance argument, to add support for non-ESP8266 boards
* Added optional begin API to override default local port
* Added end API to close UDP socket
* Changed return type of update and forceUpdate APIs to bool, and return success or failure
* Change return type of getDay, getHours, getMinutes, and getSeconds to int
Older
* Changes not recorded

## Function documentation
`getEpochTime` returns the Unix epoch, which are the seconds elapsed since 00:00:00 UTC on 1 January 1970 (leap seconds are ignored, every day is treated as having 86400 seconds). **Attention**: If you have set a time offset this time offset will be added to your epoch timestamp.
