/* If an environment variable SOURCE_DATE_EPOCH is correctly defined like
* SOURCE_DATE_EPOCH=1456304492, then returns this value, to be used as the
* 'current time', otherwise returns INVALID_EPOCH_VALUE (= 0xfffffffffULL).
- * The value should be less than about (3000 - 1970) years in seconds.
+ * Here we follow the limit in Microsoft Visual Studio 2010, that is,
