Class CurrentDateTime

public class CurrentDateTime extends SystemFunction

This class implements the XPath 2.0 functions current-date(), current-time(), and current-dateTime(), as well as the function implicit-timezone(). The value that is required is inferred from the type of result required.

Method Summary
Item	evaluateItem(XPathContext context) Evaluate in a general context
static SecondsDurationValue	getImplicitTimezone(XPathContext context) Get the implicit timezone
int	getIntrinsicDependencies() Determine the dependencies
Expression	preEvaluate(StaticContext env) preEvaluate: this method suppresses compile-time evaluation by doing nothing (because the value of the expression depends on the runtime context)
