ConstantClock

public ConstantClock(java.util.Date time)

Creates the ConstancClock object using the Date object that will be returned on subsequent calls to latch and getTime.

Parameters:

time - the Date object representing the time that will represent the current time

ConstantClock

public ConstantClock(java.lang.String timeString)

Construct a constant time clock. The parameter is interpreted as a time string. If it has a time zone specification attached, then that will be used, otherwise Java's default TimeZone will be used.

Specified by:

getTime in class Clock

Returns:

the time as specified by the constructor.

latch

public java.util.Date latch()

Description copied from class: Clock

This method gets the actual time and keeps it for later reference. Subsequent calls to getTime will return the same value (needed in operations extended in time).
