Homey's system time inaccurate to real time

Hi. I saw a thread about this in year 2017 and after reading it doesnt makes me smarter.

My homey time has 2 mins and a few seconds difference compare to my phone (and everything else). I have tried doing a manual location setting and a recovery. Both does not solve the problem. Does anyone have this issue too? pls advice

Try a PTP (that means pul the powerplug of Homey, leave it out for 15 minutes, insert the powerplug again and wait 30 minutes to let Homey startup all communications and functions)
