Regression in v47: Info tool year 2038 problem
While the Header editor can recognize any possible DateUTC allowed in EBML, it seems that the current Info tool can parse Date properly only up to 2038-01-19 03:14:07.999999999 UTC (0x1039BFC8EECAFFFF) and not 2038-01-19 03:14:08.000000000 UTC (0x1039BFC8EECB0000) and later. Also, the Info Tool can't handle the Date 1969-12-31T23:59:59 and before.
Tested on Win7. The steps to reproduce: using the Header editor, open any Matroska file and edit the Date as 2038-01-19T03:14:08 and save; open it with the Info tool. Unimportant, but v46 and before don't have this issue.
