Every airport or landing site in our database is automatically assigned a timezone of reference, based on its geographical location.
The timezone of reference is exposed in the Airport object and can be easily used by client-side applications to make time conversions.
To simplify operations, all airport Opening Hours are entered, stored and provided in Local Time. This choice is driven by the fact that airports being local businesses, they mostly follow local time patterns.
All other times are provided in Coordinated Universal Time.
