No Way to Change Timezone

[imamaad]

Description: In the react-calendar-timeline package, versions 0.30.0-beta.1 and 0.30.0-beta.2, there is no available method to change the timezone. Most of the time, the package works with timestamps, and even using dayjs, it is impossible to change the timezone.

Steps to Reproduce:

Install version 0.30.0-beta.1 or 0.30.0-beta.2 of react-calendar-timeline.
Attempt to change the timezone using dayjs or other methods.
Notice that the timezone cannot be modified, even though it’s working with timestamps.
Expected Behavior: There should be a way to adjust or set the timezone for the calendar to handle time properly based on the user's local timezone or a different specific timezone.

Actual Behavior: There is no available option to change the timezone, making it difficult to work with time-sensitive data across different time zones.
