   The new flag `skipSegmentTimeCheck: true` allows ingestion to not fail 
because of timestamp issues. As far as updating the timestamps in metadata is 
concerned, we need to find a way for users to specify the correct time-formats. 
The issue is we don't allow backward-incompatible change in the schema so if an 
user fixes the segment metadata timestamp via some new API, we won't be able to 
reflect those changes in the schema. This inconsistency may break a lot of 
things.
