When a user creates a new object or makes a selection in a date-time Date & Time field, that information is captured based on that user's current time zone. As such, if multiple users from different time zones are simultaneously triggering a concatenation that captures information from a Date & Time field or the Created On property, they may produce different results. Note that concatenations that use date-only Date & Time fields will produce the same result, regardless of a user's time zone.
Two users, one from London and one from Melbourne, are each creating objects that use the Created On property to generate the object name (i.e., OBJECT-<Created On Property>).
It's currently 18:00 on December 31, 2020 in London, and 05:00 on January 1, 2021 in Melbourne, so when both users create their objects at the same time, the concatenation produces the following results:
- London user: OBJECT-2020-12-31
- Melbourne user: OBJECT-2021-01-01
