Hi @Roger Roger
Teams will reflect the same date and time format as your device's language, date, and time settings. For example, if your device's display language is set to English (United States), the date and time in Teams will display the format used regionally in the US.
To set date and time preferences on MacOS: Select System Preferences > Language & Region.
When the meeting is sent to the participant, it will automatically adjust to the time zone set on their teams respectively to ensure that it is set on time for the other users.
For more details, you could refer to: https://support.microsoft.com/en-us/office/change-settings-in-teams.
