Time on phone keeps changing

[Hems_]

I am facing a very strange problem. 

Time on my Galaxy Note 20 automatically changes by few minutes. If you see the picture the gap is currently 54 minutes. correct time is 12:19 PM but my galaxy note 20 shows 11:25 AM. 

The gaps stays for around half an hour and then Note 20 phone automatically gets corrected to normal time.  This has been happening for sometime now. it started with the gap of around 35 minutes ( a month back) and slowly increase to 54 minutes today.  Every 1-2 day gap is increasing by a minute or two.  

I checked my time & date setting they are all taking time automatic. I checked others phone who are connected to same service provider and their phone is showing the correct time.  

Can someone please help.

Go to settings then general management go to date and time and turn off automatic date and time

But by turning off auto update, i have to manually manage the time during the travel.

What I am stating here is a big issue which is creating trouble for auto time update.  Do you have solution for the same instead of manually managing the time.
