Changelog: 3.1.0 patched - Added feature for date 3.1.0 - Added functions for changing the timeOffset and updateInterval later. Thanks @SirUli 3.0.0 - 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 2.0.0 - Add missing empty constructor for the Basic example - Remove the need for calling begin() and make sure to always try to force update if there was no update yet. 1.0.0 -Initial Release |
