18 digit timestamp to Local Time

I came across Sq-lite database.I found our date time is stored in 18 digit time-stamp.

Please help me how to convert it to Local Time. (I tried to convert it(No.of milliseconds from 1900). But i did not get it.It shows 29 days difference. I added 29 days of milliseconds to time. But time output is wrong.My assumption is, it will be NTP time.)


Here i give 18-digit time-stamp and its equivalent date time.
