Member Function Documentation

◆ datetimeFromObject()

ILIAS\MetaData\Services\DataHelper\DataHelper::datetimeFromObject ( \DateTimeImmutable $object )

Translates datetime objects to strings in the LOM-internal datetime format.

Note that LOM in ILIAS ignores the time part of any datetimes.

Implements ILIAS\MetaData\Services\DataHelper\DataHelperInterface.

Definition at line 94 of file DataHelper.php.

                                                                  : string

Here is the caller graph for this function:

◆ datetimeToObject()

ILIAS\MetaData\Services\DataHelper\DataHelper::datetimeToObject ( string $datetime )

Translates strings in the LOM-internal datetime format to datetime objects.

Note that LOM datetimes in ILIAS only consist of a date, without a time.

Implements ILIAS\MetaData\Services\DataHelper\DataHelperInterface.

Definition at line 71 of file DataHelper.php.

		?int	$months,

Here is the call graph for this function:

◆ durationToSeconds()

ILIAS\MetaData\Services\DataHelper\DataHelper::durationToSeconds ( string $duration )

Translates strings in the LOM-internal duration format to seconds.

This is only a rough estimate, as LOM-durations do not have a start date, so e.g. each month is treated as 30 days.

Implements ILIAS\MetaData\Services\DataHelper\DataHelperInterface.
