Shiyan Xu updated HUDI-9711:
----------------------------
    Description: 
Incremental timestamps should support taking in `yyyyMMddHHmmssSSS`, or ISO 
timestamps like `2025-01-02` or `2025-01-02T03:04:56.789`, etc, or epoch 
seconds or mills.

Currently, random numbers like 42 can be passed to it and go through.

It should validate the input and fail as soon as the input is not in the 
expected format. Same goes for time-travel query.

[https://github.com/apache/hudi-rs] has implemented this:
