------------------------------------
wgtmac opened a new pull request #337: ORC-434: Fix incorrect documentation for
Date/Timestamp ColumnStatistics
URL: https://github.com/apache/orc/pull/337
The old specification says Date and Timestamp ColumnStatistics stores the
difference from epoch 1/1/2015. This is incorrect and should be changed to UNIX
epoch time.

> 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.
