Method Detail

__debugInfo() public 

__debugInfo()

Returns the data that should be displayed when debugging this object

Returns

array

__toString() public 

__toString()

_formatObject() protected 

_formatObject(mixed $date, mixed $format, ?string $locale)

Returns a translated and localized date string.

Implements what IntlDateFormatter::formatObject() is in PHP 5.5+

Parameters

\DateTime|\DateTimeImmutable $date

Date.

string|int|array $format

Format.

string|null $locale

The locale name in which the date should be displayed.

Returns

string

getDefaultLocale() public static 

getDefaultLocale()

Gets the default locale.

Returns

string|null

The default locale string to be used or null.

getDiffFormatter() public static 

getDiffFormatter()

Get the difference formatter instance.

Returns

\Cake\Chronos\DifferenceFormatterInterface

i18nFormat() public 

i18nFormat(mixed $format, mixed $timezone, mixed $locale)

Returns a formatted string for this time object using the preferred format and language for the specified locale.

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: http://www.icu-project.org/apiref/icu4c/classSimpleDateFormat.html#details.

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.

Parameters

string|int|array|null $format optional

Format string.

string|\DateTimeZone|null $timezone optional

Timezone string or DateTimeZone object in which the date will be displayed. The timezone stored for this object will not be changed.

string|null $locale optional

The locale name in which the date should be displayed (e.g. pt-BR)

Returns

string|int

Formatted and translated date string

jsonSerialize() public 

jsonSerialize()

Returns a string that should be serialized when converting this object to json

Returns

string|int

nice() public 

nice(mixed $timezone, mixed $locale)

Returns a nicely formatted date string for this object.

The format to be used is stored in the static property Time::niceFormat.

Parameters

string|\DateTimeZone|null $timezone optional

Timezone string or DateTimeZone object in which the date will be displayed. The timezone stored for this object will not be changed.

string|null $locale optional

The locale name in which the date should be displayed (e.g. pt-BR)

Returns

string

Formatted date string

parseDate() public static 

parseDate(string $date, mixed $format)

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.

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

string $date

The date string to parse.

string|int|array|null $format optional

Any format accepted by IntlDateFormatter.

Returns

static|null

parseDateTime() public static 

parseDateTime(string $time, mixed $format, mixed $tz)

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.

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, -1]);

Parameters

string $time

The time string to parse.

string|int[]|null $format optional

Any format accepted by IntlDateFormatter.

\DateTimeZone|string|null $tz optional

The timezone for the instance

Returns

static|null

Throws

InvalidArgumentException
If $format is a single int instead of array of constants

parseTime(string $time, mixed $format)

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.
