Method Summary
static long getTimeOfDayFromUtc(long timeUtc)

Calculates the number of milliseconds past midnight for a given UTC time.
static long getTimeUtc(java.util.TimeZone zone, int year, int month, int date, int hourOfDay, int minute, int second, int millis)

Calculates the number of milliseconds past epoch for a given UTC time.
static java.lang.String makeDateString()

returns the current time in YYYY-MM-DD HH:MM:SS.mss format
static java.lang.String makeDateString(long date)

returns the time in YYYY-MM-DD HH:MM:SS.mss format, given a long (e.g. returned by System.currentTimeMillis)
static java.lang.String makeTimeString(long t, java.util.concurrent.TimeUnit unit)

given an elapsed time, makes it readable, eg 44d 6h, or 8s 923ms
static java.lang.String makeTimeString(long t)

given an elapsed time in ms, makes it readable, eg 44d 6h, or 8s 923ms
static java.lang.String makeTimeStringNano(long tn)

static java.lang.String makeTimeStringNanoLong(long tn)

static long parseTimeString(java.lang.String timeString)

parses a string eg '5s' or '20m 22.123ms', returning the number of milliseconds it represents (rounded); -1 on blank or never or off or false; number of millis if no units specified; otherwise throws Parse exception (including on null
static double parseTimeStringAsDouble(java.lang.String timeString)

parses a string eg '5s' or '20m 22.123ms', returning the number of milliseconds it represents; -1 on blank or never or off or false; number of millis if no units specified; otherwise throws Parse exception (including on null
static long roundFromMillis(long millis, java.util.concurrent.TimeUnit units)

static long roundFromMillis(long millis, long millisPerUnit)

static void sleep(long millis)

sleep which propagates Interrupted as unchecked
static long timeRemaining(long startTime, long maxTime)

Calculates how long until maxTime has passed since the given startTime.

Method Detail

getTimeOfDayFromUtc

public static long getTimeOfDayFromUtc(long timeUtc)
Calculates the number of milliseconds past midnight for a given UTC time.

getTimeUtc

public static long getTimeUtc(java.util.TimeZone zone, int year, int month, int date, int hourOfDay, int minute, int second, int millis)
Calculates the number of milliseconds past epoch for a given UTC time.

makeDateString

public static java.lang.String makeDateString()
returns the current time in YYYY-MM-DD HH:MM:SS.mss format

makeDateString

public static java.lang.String makeDateString(long date)
returns the time in YYYY-MM-DD HH:MM:SS.mss format, given a long (e.g. returned by System.currentTimeMillis)

makeTimeString

public static java.lang.String makeTimeString(long t, java.util.concurrent.TimeUnit unit)
given an elapsed time, makes it readable, eg 44d 6h, or 8s 923ms

makeTimeString

public static java.lang.String makeTimeString(long t)
given an elapsed time in ms, makes it readable, eg 44d 6h, or 8s 923ms

makeTimeStringNano

public static java.lang.String makeTimeStringNano(long tn)

makeTimeStringNanoLong

public static java.lang.String makeTimeStringNanoLong(long tn)

parseTimeString

public static long parseTimeString(java.lang.String timeString)
parses a string eg '5s' or '20m 22.123ms', returning the number of milliseconds it represents (rounded); -1 on blank or never or off or false; number of millis if no units specified; otherwise throws Parse exception (including on null

parseTimeStringAsDouble

public static double parseTimeStringAsDouble(java.lang.String timeString)
parses a string eg '5s' or '20m 22.123ms', returning the number of milliseconds it represents; -1 on blank or never or off or false; number of millis if no units specified; otherwise throws Parse exception (including on null

roundFromMillis

public static long roundFromMillis(long millis, java.util.concurrent.TimeUnit units)

roundFromMillis

public static long roundFromMillis(long millis, long millisPerUnit)

sleep

public static void sleep(long millis)
sleep which propagates Interrupted as unchecked

timeRemaining

public static long timeRemaining(long startTime, long maxTime)
Calculates how long until maxTime has passed since the given startTime. However, maxTime==0 is a special case (e.g. could mean wait forever), so the result is guaranteed to be only 0 if maxTime was 0; otherwise -1 will be returned.
