NAME

       msr_host_latency  -  Calculate  latency  between last sample in a Mini-SEED record and the
       host computer time.

SYNOPSIS

       #include <libmseed.h>

       double  msr_host_latency ( MSRecord *msr );

DESCRIPTION

       msr_host_latency calculates the latency in seconds of the Mini-SEED data as the difference
       between  current  time  in UTC of the host computer and the time of the last sample in the
       record.

       This routine is only really  useful  when  dealing  with  a  telemetered  data  stream  or
       something similar.

       Double  precision  is returned, but the true precision is dependent on the accuracy of the
       host system clock among other things.

RETURN VALUES

       msr_host_latency returns seconds of latency or 0.0 on error  (indistinguishable  from  0.0
       latency).

       ms_intro(3) and msr_unpack(3).
