 * It supports timezone handling in so far as luxon supports
 * timezone handling. Note: that, if able, luxon always adds
 * a timezone to a DateTime (i.e. timezone may never be undefined).
 *
 * At the moment, that means that serializing to/from iCal will
 * always apply a specific timezone (which may or may not be what
 * you want). If this is a problem for you, you can try opening
 * an issue in the rSchedule monorepo.
