Previous versions of Open Badges allowed Unix timestamps as integers. Open Badges v2.0 requires string ISO 8601 values with time zone indicators. For example, 2016-12-31T23:59:59+00:00 is a valid ISO 8601 timestamp. It contains the year, month, day, T separator, hour number 0-23, minute, optional seconds and decimal microsecond, and a time zone indicator (+/- an offset from UTC or the Z designator for UTC).",
