Method

longgetPeriodDurationInMillis(int period)
get Period Duration In Millis 
return periodDurations[period];
longGetTimeInMilliseconds(Date date)
Get Time In Milliseconds 
Calendar cal = Calendar.getInstance();
cal.setTime(date);
return cal.getTimeInMillis() + cal.getTimeZone().getOffset(cal.getTimeInMillis());
StringgetTimeStringFromMilliseconds(long millis)
get Time String From Milliseconds 
int sec = (int) ((millis / 1000L) % 60L);
int min = (int) (millis / 60000L);
return ((min < 10) ? "  " : "") + Integer.toString(min) + ':' + ((sec < 10) ? "0" : "")
        + Integer.toString(sec);
longgetTimeZoneOffSetInMillisecond(String dateString)
get Time Zone Off Set In Millisecond 
String timeZoneOffSetInHour = getTimeZoneOffSetInHour(dateString);
if (timeZoneOffSetInHour.length() == 5) {
    String flag = timeZoneOffSetInHour.substring(0, 1);
    Integer hour = Integer.parseInt(timeZoneOffSetInHour.substring(1, 3));
    Integer minute = Integer.parseInt(timeZoneOffSetInHour.substring(3, 5));
    if (DATE_SEPARATOR_MINUS.equals(flag)) {
        hour = -hour;
        minute = -minute;
...
longgetUnitLengthMillis(String unit)
Gets the length of the given unit in milliseconds. 
unit = unit.trim();
if (unit.equals("seconds") || unit.equals("second") || unit.equals("secs") || unit.equals("sec")
        || unit.equals("s")) {
    return 1000;

booleanhasExpiredMillis(long now, long eventTime, long timeBuffer)
Test whether a given event has timed out (in milliseconds). 
return (eventTime + timeBuffer) < now;
longhhmmssToMillis(String text)
hhmmss To Millis 
if (text.matches("^\\d\\d:\\d\\d:\\d\\d$")) {
    int hours = Integer.parseInt(text.substring(0, 2));
    int minutes = Integer.parseInt(text.substring(3, 5));
    int seconds = Integer.parseInt(text.substring(6, 8));

human Date To Milliseconds Without Exception 
try {
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss,SSS");
    sdf.setTimeZone(CURRENT_TIME_ZONE);
    Date d = sdf.parse(date);
    return d.getTime();
} catch (ParseException ex) {
    return 0L;
booleanisSameSecondOfMillis(final long ms1, final long ms2)
is Same Second Of Millis 
final long interval = ms1 - ms2;
return interval < 1000L && interval > -1000L && (ms1 / 1000L == ms2 / 1000L);
StringlongToDate(long millis)
Turns a long variable that represents time into a String 
Date date = new Date(millis);
SimpleDateFormat dateFormat = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss z", Locale.US);
dateFormat.setTimeZone(TimeZone.getDefault().getTimeZone("GMT"));
return dateFormat.format(date);
