public DateTools.OffsetTimeSource(DateTime startDate)

Create an offset to apply to the real current time. The DateTime passed is the starting time to jump to as soon as this DateTools.TimeSource takes effect.

Parameters:

startDate - the date to use to calculate the offset from now.

Method Detail

getTime

public long getTime()

Description copied from interface: DateTools.TimeSource

Returns the number of milliseconds since 1970-01-01. Some implementations may choose to not use System.currentTimeMillis() as the source! This flexibility allows a VM-wide offset or time acceleration to be implemented. Keep in mind that if time is accelerated, wait(long msTimeout) and Thread.sleep(long msDuration) times requested throughout the VM will likely last too long.
