I was reading a question on Travel.SE. The asker was asking whether the time on his ticket was in Daylight Savings Time or in standard time. I would imagine flight schedules are supposed to be time-zone/DST agnostic so as to avoid any potential confusion and timezone conversions.

A commenter mentioned UTC time, which makes sense to me.

So my question is: is there a standard time zone or other time standard used for tickets and/or flight schedules?

    $\begingroup$ I call time on my ticket as my flight schedule. Are you asking about flight schedule as seen from passenger or pilot? $\endgroup$

Customer facing documents like boarding passes and itineraries typically show local times for ease of use. Just use airport clocks. I would not trust the flying public to compute UTC. It would be chaos.

Crew facing documents will usually be set to UTC, or zulu time.
