Constructor & Destructor Documentation

◆ Time() [1/4]

juce::Time::Time ( )

default

Creates a Time object. This default constructor creates a time of midnight Jan 1st 1970 UTC, (which is represented internally as 0ms). To create a time object representing the current time, use getCurrentTime().

See also: getCurrentTime

◆ Time() [2/4]

juce::Time::Time ( int64 millisecondsSinceEpoch )

explicitnoexcept

Creates a time based on a number of milliseconds. To create a time object set to the current time, use getCurrentTime().

Parameters

millisecondsSinceEpoch the number of milliseconds since the unix 'epoch' (midnight Jan 1st 1970 UTC).

See also: getCurrentTime, currentTimeMillis

◆ Time() [3/4]

juce::Time::Time	(	int	year,
		int	month,
		int	day,
		int	hours,
		int	minutes,
		int	seconds = 0,
		int	milliseconds = 0,
		bool	useLocalTime = true )

noexcept

Creates a time from a set of date components.

Parameters

year	the year, in 4-digit format, e.g. 2004
month	the month, in the range 0 to 11
day	the day of the month, in the range 1 to 31
hours	hours in 24-hour clock format, 0 to 23
minutes	minutes 0 to 59
seconds	seconds 0 to 59
milliseconds	milliseconds 0 to 999
useLocalTime	if true, assume input is in this machine's local timezone if false, assume input is in UTC.

◆ Time() [4/4]

juce::Time::Time ( const Time & )

default

◆ ~Time()

juce::Time::~Time ( )

default

Member Function Documentation

◆ currentTimeMillis()

int64 juce::Time::currentTimeMillis ( )

staticnoexcept

Returns the current system time.

Returns the number of milliseconds since midnight Jan 1st 1970 UTC.

Should be accurate to within a few millisecs, depending on platform, hardware, etc.

◆ formatted()

String juce::Time::formatted ( const String & format ) const

Converts this date/time to a string with a user-defined format.

This uses the C strftime() function to format this time as a string. To save you looking it up, these are the escape codes that strftime uses (other codes might work on some platforms and not others, but these are the common ones):

a is replaced by the locale's abbreviated weekday name.
A is replaced by the locale's full weekday name.
b is replaced by the locale's abbreviated month name.
B is replaced by the locale's full month name.
c is replaced by the locale's appropriate date and time representation.
d is replaced by the day of the month as a decimal number [01,31].
H is replaced by the hour (24-hour clock) as a decimal number [00,23].
I is replaced by the hour (12-hour clock) as a decimal number [01,12].
j is replaced by the day of the year as a decimal number [001,366].
m is replaced by the month as a decimal number [01,12].
M is replaced by the minute as a decimal number [00,59].
p is replaced by the locale's equivalent of either a.m. or p.m.
S is replaced by the second as a decimal number [00,60].
U is replaced by the week number of the year (Sunday as the first day of the week) as a decimal number [00,53].
w is replaced by the weekday as a decimal number [0,6], with 0 representing Sunday.
W is replaced by the week number of the year (Monday as the first day of the week) as a decimal number [00,53]. All days in a new year preceding the first Monday are considered to be in week 0.
x is replaced by the locale's appropriate date representation.
X is replaced by the locale's appropriate time representation.
y is replaced by the year without century as a decimal number [00,99].
Y is replaced by the year with century as a decimal number.
Z is replaced by the timezone name or abbreviation, or by no bytes if no timezone information exists.
%% is replaced by %.

◆ fromISO8601()

Time juce::Time::fromISO8601 ( StringRef iso8601 )

static

Parses an ISO-8601 string and returns it as a Time.

◆ getApproximateMillisecondCounter()

uint32 juce::Time::getApproximateMillisecondCounter ( )

staticnoexcept

Less-accurate but faster version of getMillisecondCounter().

This will return the last value that getMillisecondCounter() returned, so doesn't need to make a system call, but is less accurate - it shouldn't be more than 100ms away from the correct time, though, so is still accurate enough for a lot of purposes.

See also: getMillisecondCounter

◆ getCompilationDate()

Time juce::Time::getCompilationDate ( )

static

Returns a Time based on the value of the DATE macro when this module was compiled

◆ getCurrentTime()

Time JUCE_CALLTYPE juce::Time::getCurrentTime ( )

staticnoexcept

Returns a Time object that is set to the current system time.

This may not be monotonic, as the system time can change at any moment. You should therefore not use this method for measuring time intervals.

See also: currentTimeMillis

◆ getDayOfMonth()

int juce::Time::getDayOfMonth ( ) const

noexcept

Returns the day of the month (in this machine's local timezone). The value returned is in the range 1 to 31.

◆ getDayOfWeek()

int juce::Time::getDayOfWeek ( ) const

noexcept

Returns the number of the day of the week (in this machine's local timezone). The value returned is in the range 0 to 6 (0 = sunday, 1 = monday, etc).

◆ getDayOfYear()

int juce::Time::getDayOfYear ( ) const

noexcept

Returns the number of the day of the year (in this machine's local timezone). The value returned is in the range 0 to 365.

◆ getHighResolutionTicks()

int64 juce::Time::getHighResolutionTicks ( )

staticnoexcept

Returns the current high-resolution counter's tick-count.

This is a similar idea to getMillisecondCounter(), but with a higher resolution.

See also: getHighResolutionTicksPerSecond, highResolutionTicksToSeconds, secondsToHighResolutionTicks

◆ getHighResolutionTicksPerSecond()

int64 juce::Time::getHighResolutionTicksPerSecond ( )

staticnoexcept

Returns the resolution of the high-resolution counter in ticks per second.

See also: getHighResolutionTicks, highResolutionTicksToSeconds, secondsToHighResolutionTicks

◆ getHours()

int juce::Time::getHours ( ) const

noexcept

Returns the number of hours since midnight (in this machine's local timezone). This is in 24-hour clock format, in the range 0 to 23.

See also: getHoursInAmPmFormat, isAfternoon

◆ getHoursInAmPmFormat()

int juce::Time::getHoursInAmPmFormat ( ) const

noexcept

Returns the hours in 12-hour clock format (in this machine's local timezone). This will return a value 1 to 12 - use isAfternoon() to find out whether this is in the afternoon or morning.

See also: getHours, isAfternoon

◆ getMillisecondCounter()

uint32 juce::Time::getMillisecondCounter ( )

staticnoexcept

Returns the number of millisecs since a fixed event (usually system startup).

This returns a monotonically increasing value which is unaffected by changes to the system clock. It should be accurate to within a few millisecs, depending on platform, hardware, etc.

Being a 32-bit return value, it will of course wrap back to 0 after 2^32 seconds of uptime, so be careful to take that into account. If you need a 64-bit time, you can use currentTimeMillis() instead.

See also: getApproximateMillisecondCounter

◆ getMillisecondCounterHiRes()

double juce::Time::getMillisecondCounterHiRes ( )

staticnoexcept

Returns the number of millisecs since a fixed event (usually system startup).

This has the same function as getMillisecondCounter(), but returns a more accurate value, using a higher-resolution timer if one is available.

See also: getMillisecondCounter

◆ getMilliseconds()

int juce::Time::getMilliseconds ( ) const

noexcept

Returns the number of milliseconds, 0 to 999.

Unlike toMilliseconds(), this just returns the position within the current second rather than the total number since the epoch.

See also: toMilliseconds

◆ getMinutes()

noexcept

Returns the number of minutes, 0 to 59 (in this machine's local timezone).

◆ getMonth()

int juce::Time::getMonth ( ) const

noexcept

Returns the number of the month (in this machine's local timezone). The value returned is in the range 0 to 11.
