jerrypeng commented on issue #4823: Support timezone information in Pulsar URL: https://github.com/apache/pulsar/issues/4823#issuecomment-515309785 I have a couple questions just to understand the rational behind having timezones with timestamp: 1. Since all unix timestamp are in UTC time does it make sense to have timezone information for publish_time especially since it is set by the system? In presto, for a timestamp field, by default it displays the time in the local timezone anyways 2. The user can set event_time, and from my understanding, users can offset the unix timestamp in UTC time by certain number of hours to correspond to a particular timezone. Is this a best practice? I am not an expert in how time should be represented in a database. Just searching what other have said online: https://justatheory.com/2012/04/postgres-use-timestamptz/ https://medium.com/@vivekmadurai/how-to-deal-with-date-and-time-across-time-zones-39b1bd747f35 Should we set or assume every timestamp to be in UTC time for consistency sake? Presto will display a timestamp field in local time
