Rtc chip with milliseconds

WebIf the time is passed in milliseconds, the alarm can be repeated by setting the keyword argument repeat to True. The milliseconds are counted from the current date-time of the RTC. RTC.alarm_left (alarm_id=0): returns the number of milliseconds to the alarm. RTC.cancel (alarm_id=0): used to cancel a running alarm.
