Methods
__construct()
Create a new Date instance.
public
__construct([DateTime|DateTimeImmutable|string|int|null $time = 'now' ][, DateTimeZone|string|null $tz = null ]) : mixed
You can specify the timezone for the $time parameter. This timezone will not be used in any future modifications to the Date instance.
The $timezone
parameter is ignored if $time
is a DateTimeInterface
instance.
Date instances lack time components, however due to limitations in PHP's internal Datetime object the time will always be set to 00:00:00, and the timezone will always be the server local time. Normalizing the timezone allows for subtraction/addition to have deterministic results.
Parameters
- $time : DateTime|DateTimeImmutable|string|int|null = 'now'
-
Fixed or relative time
- $tz : DateTimeZone|string|null = null
-
The timezone in which the date is taken. Ignored if
$time
is a DateTimeInterface instance.
__debugInfo()
Returns the data that should be displayed when debugging this object
public
__debugInfo() : array<string, mixed>
Return values
array<string, mixed>__toString()
public
__toString() : string
Tags
Return values

When comparing a value in the past to default now: 1 hour ago 5 months ago
When comparing a value in the future to default now: 1 hour from now 5 months from now
When comparing a value in the past to another value: 1 hour before 5 months before
When comparing a value in the future to another value: 1 hour after 5 months after
Parameters
- $other : ChronosInterface|null = null
-
The datetime to compare with.
- $absolute : bool = false
-
removes time difference modifiers ago, after, etc
Return values
stringdisableLenientParsing()

public
static disableLenientParsing() : void
enableLenientParsing()
Enables lenient parsing for locale formats.
public
static enableLenientParsing() : void
getDefaultLocale()
Gets the default locale.
public
static getDefaultLocale() : string|null
Return values
string|null —The default locale string to be used or null.
getDiffFormatter()
Get the difference formatter instance.
public
static getDiffFormatter() : DifferenceFormatterInterface
Return values
DifferenceFormatterInterfacei18nFormat()
Returns a formatted string for this time object using the preferred format and language for the specified locale.
public
i18nFormat([array<string|int, int>|string|int|null $format = null ][, DateTimeZone|string|null $timezone = null ][, string|null $locale = null ]) : string|int
It is possible to specify the desired format for the string to be displayed.
You can either pass IntlDateFormatter
constants as the first argument of this
function, or pass a full ICU date formatting string as specified in the following
resource: https://unicode-org.github.io/icu/userguide/format_parse/datetime/#datetime-format-syntax.
Additional to IntlDateFormatter
constants and date formatting string you can use
Time::UNIX_TIMESTAMP_FORMAT to get a unix timestamp
Examples
$time = new Time('2014-04-20 22:10');
$time->i18nFormat(); // outputs '4/20/14, 10:10 PM' for the en-US locale
$time->i18nFormat(\IntlDateFormatter::FULL); // Use the full date and time format
$time->i18nFormat([\IntlDateFormatter::FULL, \IntlDateFormatter::SHORT]); // Use full date but short time format
$time->i18nFormat('yyyy-MM-dd HH:mm:ss'); // outputs '2014-04-20 22:10'
$time->i18nFormat(Time::UNIX_TIMESTAMP_FORMAT); // outputs '1398031800'
You can control the default format used through Time::setToStringFormat()
.
You can read about the available IntlDateFormatter constants at https://secure.php.net/manual/en/class.intldateformatter.php
If you need to display the date in a different timezone than the one being used for this Time object without altering its internal state, you can pass a timezone string or object as the second parameter.
Finally, should you need to use a different locale for displaying this time object, pass a locale string as the third parameter to this function.
Examples
$time = new Time('2014-04-20 22:10');
$time->i18nFormat(null, null, 'de-DE');
$time->i18nFormat(\IntlDateFormatter::FULL, 'Europe/Berlin', 'de-DE');
You can control the default locale used through Time::setDefaultLocale()
.
If empty, the default will be taken from the intl.default_locale
ini config.

Return values
string —Formatted date string
parseDate()
Returns a new Time object after parsing the provided $date string based on the passed or configured date time format. This method is locale dependent, Any string that is passed to this function will be interpreted as a locale dependent string.
public
static parseDate(string $date[, array<string|int, mixed>|string|int|null $format = null ]) : static|null
When no $format is provided, the wordFormat
format will be used.
If it was impossible to parse the provided time, null will be returned.
Example:
$time = Time::parseDate('10/13/2013');
$time = Time::parseDate('13 Oct, 2013', 'dd MMM, y');
$time = Time::parseDate('13 Oct, 2013', IntlDateFormatter::SHORT);
Parameters
- $date : string
-
The date string to parse.
- $format : array<string|int, mixed>|string|int|null = null
-
Any format accepted by IntlDateFormatter.
Return values
static|nullparseDateTime()
Returns a new Time object after parsing the provided time string based on the passed or configured date time format. This method is locale dependent, Any string that is passed to this function will be interpreted as a locale dependent string.
public
static parseDateTime(string $time[, array<string|int, int>|string|int|null $format = null ][, DateTimeZone|string|null $tz = null ]) : static|null
When no $format is provided, the toString
format will be used.
Unlike DateTime, the time zone of the returned instance is always converted
to $tz
(default time zone if null) even if the $time
string specified a
time zone. This is a limitation of IntlDateFormatter.
If it was impossible to parse the provided time, null will be returned.
Example:
$time = Time::parseDateTime('10/13/2013 12:54am');
$time = Time::parseDateTime('13 Oct, 2013 13:54', 'dd MMM, y H:mm');
$time = Time::parseDateTime('10/10/2015', [IntlDateFormatter::SHORT, IntlDateFormatter::NONE]);

timeAgoInWords()
Returns either a relative or a formatted absolute date depending on the difference between the current date and this object.
public
timeAgoInWords([array<string, mixed> $options = [] ]) : string
Options:
-
from
=> another Date object representing the "now" date -
format
=> a fall back format if the relative time is longer than the duration specified by end -
accuracy
=> Specifies how accurate the date should be described (array)- year => The format if years > 0 (default "day")
- month => The format if months > 0 (default "day")
- week => The format if weeks > 0 (default "day")
- day => The format if weeks > 0 (default "day")

relativeString
=> The printf compatible string when outputting relative date -
absoluteString

timezone
=> The user timezone the timestamp should be formatted in.
Relative dates look something like this:
- 3 weeks, 4 days ago
- 1 day ago
Default date formatting is d/M/YY e.g: on 18/2/09. Formatting is done internally using
i18nFormat
, see the method for the valid formatting strings.
The returned string includes 'ago' or 'on' and assumes you'll properly add a word like 'Posted ' before the function output.
NOTE: If the difference is one week or more, the lowest level of accuracy is day.

-
Array of options.
Return values
string —Relative time string.
