addGuesser

private addGuesser(string $key, \Sabre\VObject\TimezoneGuesser\TimezoneGuesser $guesser): void

Parameters:

Parameter Type Description
$key string
$guesser \Sabre\VObject\TimezoneGuesser\TimezoneGuesser

addFinder

private addFinder(string $key, \Sabre\VObject\TimezoneGuesser\TimezoneFinder $finder): void

Parameters:

Parameter Type Description
$key string
$finder \Sabre\VObject\TimezoneGuesser\TimezoneFinder

findTimeZone

This method will try to find out the correct timezone for an iCalendar date-time value.

private findTimeZone(string $tzid, \Sabre\VObject\Component $vcalendar = null, bool $failIfUncertain = false): \DateTimeZone

You must pass the contents of the TZID parameter, as well as the full calendar.

If the lookup fails, this method will return the default PHP timezone (as configured using date_default_timezone_set, or the date.timezone ini setting).

Alternatively, if $failIfUncertain is set to true, it will throw an exception if we cannot accurately determine the timezone.

Parameters:

Parameter Type Description
$tzid string
$vcalendar \Sabre\VObject\Component
$failIfUncertain bool

This method will load in all the tz mapping information, if it's not yet done.

public static loadTzMaps(): mixed

  • This method is static.

  • Warning: this method is deprecated. This means that this method will likely be removed in a future version.

getIdentifiersBC

This method returns an array of timezone identifiers, that are supported by DateTimeZone(), but not returned by DateTimeZone::listIdentifiers().

public static getIdentifiersBC(): array

We're not using DateTimeZone::listIdentifiers(DateTimeZone::ALL_WITH_BC) because: - It's not supported by some PHP versions as well as HHVM. - It also returns identifiers, that are invalid values for new DateTimeZone() on some PHP versions. (See timezonedata/php-bc.php and timezonedata php-workaround.php)
