-----------------------------------

I see we are using checkedMultiply now. Is this resolved?

> When converting from Joda Instant/Datetime, what can be gotten is epoch 
> millis, but conversions require epoch micros, so * 1000L is applied, but it 
> definitely has overflow issue and need to be handle appropriately.
> This issue exists in zetasql planner.
