Carbon::setTestNow

Set a Carbon instance (real or mock) to be returned when a "now" instance is created. The provided instance will be returned specifically under the following conditions:

A call to the static now() method, ex. Carbon::now()
When a null (or blank string) is passed to the constructor or parse(), ex. new Carbon(null)
When the string "now" is passed to the constructor or parse(), ex. new Carbon('now')
When a string containing the desired time is passed to Carbon::parse().

Note the timezone parameter was left out of the examples above and has no affect as the mock value will be returned regardless of its value.

Only the moment is mocked with setTestNow(), the timezone will still be the one passed as parameter of date_default_timezone_get() as a fallback (see setTestNowAndTimezone()).

To clear the test instance call this method using the default parameter of null.

/!\ Use this method for unit tests only.

Parameters

$testNow \DateTimeInterface|\Closure|static|string|false|null real or mock Carbon instance

History	Version	Description
Prototype changed	3.0.0	`mixed $testNow = null`
Prototype changed	1.22.0	`$testNow = null`

Carbon::setTestNowAndTimezone

Set a Carbon instance (real or mock) to be returned when a "now" instance is created. The provided instance will be returned specifically under the following conditions:

A call to the static now() method, ex. Carbon::now()
When a null (or blank string) is passed to the constructor or parse(), ex. new Carbon(null)
When the string "now" is passed to the constructor or parse(), ex. new Carbon('now')
When a string containing the desired time is passed to Carbon::parse().

It will also align default timezone (e.g. call date_default_timezone_set()) with the second argument or if null, with the timezone of the given date object.

To clear the test instance call this method using the default parameter of null.

/!\ Use this method for unit tests only.

Parameters

- 'syntax' entry (see below)
- 'short' entry (see below)
- 'parts' entry (see below)
- 'options' entry (see below)
- 'join' entry determines how to join multiple parts of the string - if $join is a string, it's used as a joiner glue - if $join is a callable/closure, it get the list of string and should return a string - if $join is an array, the first item will be the default glue, and the second item will be used instead of the glue for the last item - if $join is true, it will be guessed from the locale ('list' translation file entry) - if $join is missing, a space will be used as glue
