IEC 61850 Timestamp to overflow in 2038?

In 61850-7-2 Edition 1 the definition of TimeStamp.SecondSinceEpoch is an INT32, which represents seconds since 1/1/1970. This will overflow in 2038, at which time equipment now being developed will be in use.

The Timestamp type in IEC 61850-7-2 Edition 2 is INT32U. The timestamp will not overflow until 2106.
