How do I change the time zone on automation action...

[Xing]

hi dear folks,
I want to ask a question relates about the “include a time filed” dependents on the date field.
I’m not sure the time filed which I modified was on the local time where I edited, or it will be converted automatically on the local time where I am.

For instance,
If I create a date/time when I am in New York, saying as May 23, 2019, 20:30, and I also created a Calendar view which I also subscripted on my Apple iCal.
The questions comes
When I travel to Los Angeles, will the calendar show this event on May 23, 2019, 20:30 on NY time, or LA time?

Thank you.
