Hello @SaiGaneshReddy,
profile.browserTime specifies only the respective browser time. With this you can e.g. determine if it is morning or rather evening for the user and accordingly display e.g. personalizations.
You can write your own script so a kind of counter. There are several possibilities how to build it - like listening to the beforeunload event, etc.. Here you must also know whether a counter can be reset (if desired). Was then rather that finally in the profile in ranges deposit e.g.
less than 15 seconds
15 to 29 seconds
30 to 59 seconds
1 to 3 minutes
3 to 5 minutes
5 to 10 minutes
10 to 15 minutes
15 to 20 minutes
20 to 30 minutes
more than 30 minutes
