QuickRecord: Fix crash on other languages

With the new multiple recordings,
	some languages parse the DateFormat
	where it was being split by the regex
	and incompatible recording files were
	formed.  Use a java formatted regex
	to remove the possibility of slashes
	sneaking in for different languages
