      Description

      In the documentation of ORC specification, the following two statements are wrong:

      • Date columns record the minimum and maximum values as the number of days since the epoch (1/1/2015).
      • Timestamp columns record the minimum and maximum values as the number of milliseconds since the epoch (1/1/2015).

      The correct epoch is UNIX time epoch which is January 1, 1970 in UTC.
