Description

The list of methods to do Milliseconds are organized into topic(s).

Method

longdurationInMillis(long startNano)
duration In Millis 
final long endNano = System.nanoTime();
return (endNano - startNano) / 1000000;
StringelapsedMillis(long milliseconds)
Returns a string representation of the specified elapsed time in the format "H hours M minutes S seconds". 
return elapsedNanos(1000000 * milliseconds);
longelapsedMillis(long startTime)
elapsed Millis 
return (long) elapsedTime(startTime, System.nanoTime(), 1e6);
longelapsedMillis(long t0nanos, long t1nanos)
Get the elapsed milliseconds between two nano times 
return (t1nanos - t0nanos) / 1000000;
voidensureSleepMillis(long millis)
Ensures the current thread sleeps at least the given milliseconds before returning from this method. 
if (millis < 1)
    return;
long now = System.currentTimeMillis();
final long targetTime = now + millis;
do {
    Thread.sleep(millis);
    millis = targetTime - System.currentTimeMillis();
} while (millis > 0);
...
StringexpensiveMethodTakingMillis(final int millis)
expensive Method Taking Millis 
try {
    Thread.sleep(millis);
    return "hi";
} catch (InterruptedException e) {
    throw new IllegalStateException(e);
longfiletimeToMillis(long filetime)
Converts a 64-bit NTFS time value (number of 100-nanosecond intervals since January 1, 1601 UTC) to a Java time value (number of milliseconds since January 1, 1970 UTC.) 
filetime -= 116444736000000000L;
if (filetime < 0) {
    filetime = -1 - ((-filetime - 1) / 10000);
} else {
    filetime = filetime / 10000;
return filetime;
StringformatDateMillis(long millis)
format Date Millis 
String weekdays = "SunMonTueWedThuFriSat";
String months = "JanFebMarAprMayJunJulAugSepOctNovDec";
Calendar cal = Calendar.getInstance();
cal.setTime(new Date(millis));
return weekdays.substring((cal.get(Calendar.DAY_OF_WEEK) - 1) * 3).substring(0, 3) + " "
        + months.substring(cal.get(Calendar.MONTH) * 3).substring(0, 3) + " " + cal.get(Calendar.DATE) + " "
        + cal.get(Calendar.HOUR_OF_DAY) + ":" + (cal.get(Calendar.MINUTE) < 10 ? "0" : "")
        + cal.get(Calendar.MINUTE) + " " + cal.get(Calendar.YEAR);
...
StringFormatDateTime(Calendar p_date, String p_seperator, boolean p_showMilliseconds)
Format Date Time 
StringBuilder t_dateTime = new StringBuilder();
t_dateTime.append(FormatDate(p_date, p_seperator) + " ");
t_dateTime.append(FormatTime(p_date.get(Calendar.HOUR_OF_DAY), p_date.get(Calendar.MINUTE),
        p_date.get(Calendar.SECOND), (p_showMilliseconds ? p_date.get(Calendar.MILLISECOND) : -1)));
return t_dateTime.toString();
longfractionOfDayToMilliseconds(float fFractionOfDay)
Convert a duration that is based on fraction-of-a-day to milliseconds. 
float fDuration = (fFractionOfDay * 24 * 60 * 60 * 1000);
return (long) fDuration;
