Sync Time if no internet

[newwolf]

Could it be possible to make WLED sync the internal time from your device time. Like on the press of a button (sync device time) and it grabs the local device time (from the browser or something?)

Should be very nice when we are at a internetless location, because we use the light as a night/wakeup light with timers for our kid.

It does that when you connect to ESP using phone or PC when NTP is not defined or WLED opens AP.

... plus there is the RTC usermod. Just make a custom build with RTC usermod, attach a DS3231 or DS1307 module to I2C, and your WLED will take the time/date from the realtime clock chip at startup.
