Introducing support for timestamps in custom Properties and User Traits

You can now include any timestamp field in event Custom Properties and User Traits, enabling you to extend the information collected about these events. The timestamp should be provided as a string in ISO8601 format, which will be correctly identified and parsed.

This feature is particularly useful in scenarios such as account verification, where detailed information about the process, including its duration, needs to be stored. For instance, you can send the verification_process_started_at timestamp as part of the event's custom properties. Once the verification is complete, you can add the verified_at timestamp to User Traits.
