re PR libgcj/1358 (java.util.Date.toString() doesn't seem to behave properly.)

	Fix for PR libgcj/1358:
	* java/lang/System.java: Update Copyright date properly.
	* java/util/Calendar.java: Fix typo in comment.
	(set): Set 24-hour clock hour instead of 12-hour clock hour.
	* java/util/GregorianCalendar.java (GregorianCalendar): Properly
	initialize times.  Spec says to set H:M:S values to zero only if
	a date is given.
	* java/util/TimeZone.java (getDefaultDisplayName): Casts to char
	needed for evaluating numbers '0' to '9' in printouts of GMT offsets.
	* java/util/natGregorianCalendar.cc (computeTime): Properly handle
	timezones and GMT offsets, being careful to account for units of
	milliseconds vs. seconds.
