Defined in:
lib/openc3/core_ext/time.rb

.ccsds2mdy(day, ms, us) ⇒ Array<Year, Month, Day, Hour, Minute, Second, Microsecond>

Convert a CCSDS Date to mdy format Note that an array is returned rather than a Time object because Time objects cannot represent all possible CCSDS dates

Parameters:

  • day (Float) —

    CCSDS day

  • ms (Integer) —

    CCSDS milliseconds

  • us (Integer) —

    CCSDS microseconds
