---------------------------------------------------------------------
Its a consideration for existing users. Any user who would have created a
keyspace before this fix, will have timestamps in whatever System.nanoTime()
returns. The bigger you make the timestamp, the less users will be stuck
attempting to fix their timestamps so they can update their schema (I guess
using sstable2json?). Plus, its consistent with columns :)

> From nanoTime() description:
> "The value returned represents nanoseconds since some fixed but arbitrary
> time (perhaps in the future, so values may be negative). This method provides
> nanosecond precision, but not necessarily nanosecond accuracy. No guarantees
> are made about how frequently values change."
