private static final long MIN_USE_DATE_OF_TIMEZONE = 1514764800000L; // 1/1/2018 00:00 UTC * metadata Android holds for each time zone.
*
* notUsedAfter exists because some time zones effectively "merge" with other time zones after
* a given point in time (i.e. they have identical transitions, offsets, etc.). After that
* point we only need to show one of the functionally identical ones.
*
* Rather than using System.currentTimeMillis(), UX folks asked for consistent behavior and so
* a timestamp known to be in the recent past is used. This should be updated occasionally but
* it doesn't have to be very often.
