# 2 possible algos: at each new timestamp, update run/queue/sleep time for all threads vs update
# only the right process. 2nd algo is still easy
# because we have duration of this state.
# this presents run, queued, sleep time of processes sorted by run time. REL time starts when
# process was created while ABS time if from beginning. Therefore elapsed time between start and
# process creation is added as sleep time
