Method Detail
-
currentElapsedTime
public static long currentElapsedTime()
Returns time in milliseconds as does System.currentTimeMillis(), but uses elapsed time from an arbitrary epoch more like System.nanoTime(). The difference is that if somebody changes the system clock, Time.currentElapsedTime will change but nanoTime won't. On the other hand, all of ZK assumes that time is measured in milliseconds.- Returns:
- The time in milliseconds from some arbitrary point in time.
-
currentWallTime
public static long currentWallTime()
Explicitly returns system dependent current wall time.- Returns:
- Current time in msec.
-
elapsedTimeToDate
public static Date elapsedTimeToDate(long elapsedTime)
This is to convert the elapsedTime to a Date.- Returns:
- A date object indicated by the elapsedTime.
