Package org.yamcs.simulator.pus

Class PusTime

java.lang.Object

org.yamcs.simulator.pus.PusTime

All Implemented Interfaces:

Comparable<PusTime>

public class PusTime
extends Object
implements Comparable<PusTime>

PUS time used by the simulator is 1 byte for the pfield, 4 bytes seconds and 3 bytes sub-second.

The seconds are counted from the Unix epoch (1970-01-01), so the value is a real on-board time that the ground can interpret directly (preprocessor timeEncoding: {epoch: UNIX}) without needing time correlation. It advances with a small constant drift relative to the host clock to keep the correlation demo in the pus-frames example meaningful.
