Reindex would use timeValueNanos(System.nanoTime()). The intended use for TimeValue is as a duration, not as absolute time. In particular, this could result in negative TimeValue's, being unsupported in elastic#53913.

This was interesting anyway since this constructor TimeValue(long) is intended to be passed a value that represents milliseconds, which System#nanoTime does not.

Yeah, I double checked that and I introduced that "bug" when refactoring this last year. It never showed up, since the variable ends up unused anyway...

The 6.8 backport is likely a redo (but this was a simple change), since the structure changed in 7.x
