Stop Calendar from changing time-zone

I use Google Calendar instead of the stock calendar on my LG G5. I travel internationally on a weekly basis, and the Calendar app would automatically adjust the calendar events' scheduled time once I landed to a different time zone (if Auto Date & Time is on) or once I adjusted the time zone manually (if Auto Date & Time is off). The fact that Calendar Events' times got changed is utterly impractical and annoying. For example, I would add an event at 8pm on a future date in that destination of a different time zone, and once I land there, the Calendar event time will be changed to 2pm. This throws off the timing of all my events. I almost missed several flights because the alarm did not go off at the right time, especially in connected flights crossing multiple time zones. How can I stop Calendar from doing that? If I recall, iPhone does not do that.
