Description
I'm using version 01.01.01 - build 0000f4.
I've enabled NTP with servers: pool.ntp.org and time.nist.gov, and I'm connected to wifi, but the main clock quickly falls behind.
To resync the datetime, I've tried to restart device, disconnect/reconnect wifi, disable/re-enable NTP...
Nothing works.
I'm guessing the NTP won't resync unless the timedelta is above a certain threshold ?
How can I resync the clock ?

Research direction
Start by locating the firmware's NTP configuration and clock-synchronization logic, then reproduce the reported drift with the listed servers and Wi-Fi enabled. Done means determining why resynchronization does not occur and documenting or fixing the behavior, with a repeatable verification on the device.
