When the '-v' or '--test-position' options are used, the 'tstamp' is shown as zero. Unconditionally enable the timestamps and choose the timestamp time based on the 'monotonic' variable. Example log: Status(R/W) (standalone avail=36 delay=924): state : RUNNING trigger_time: 2045.504937 tstamp : 2190.754602 delay : 924 avail : 36 avail_max : 444 Status(R/W) (standalone avail=44 delay=912): state : RUNNING trigger_time: 2045.504937 tstamp : 2190.754852 delay : 912 avail : 48 avail_max : 48 underrun!!!
