dbTouch()

Each entry in the Database for Contents has a timestamp with the date and time of the most recent change. This timestamp is updated with dbTouch(), without the saved contents being changed.

void dbTouch(string key)

This function can be used, for example, in combination with an extended selection. The selected option can therefore be given a current timestamp – options that have not been selected for a certain amount of time can then be deleted based on this timestamp.
