How data and time field values are visible to different time zone persons?

[Manikantahere]

In my profile, I see my time zone as US/Central, but when I raise a request and enter the date and time fields, I see Indian time only. 

How does it generally work? By the way, how do the same values appear for someone in a different time zone when they open the request and view the date and time fields?

by default date/time are stored in GMT/UTC, but displayed as per logged in user's timezone

When users open the date/time values in portal etc, they see the date/time values converted from GMT to their local timezone

check this for explanation

May I know difference between system time zone and user preference time zone? How it displays based on it?

@Manikantahere 

it's already explained in the links I shared.

System timezone -> GMT

User timezone-> as per his/her profile timezone
