Details
1588 has too much resolution to represent in a single floating-point value, so the alarm times are split
into two values (seconds and fractional seconds).
Example
sec,ns = ptp.time()
schedule.alarm[1].ptpseconds = sec + 30
Create an alarm to occur 30 seconds from
current time in PTP seconds.
