Closed since no reports on current version, or in 17 mmonhts.

The original submitter said:

I had a look at gpsdclient.c, at line 75

>     dsec = (int)(fdsec * 10000.0);
>     (void)snprintf(str, sizeof(str), "%3d %02d' %02d.%05d\"", deg, min,
> sec,
>            dsec);

in gpsd-3.16 fdsec was multiplied by 1000.0 and the format specifier for dsec was "%03d", so there is a missing zero at line 75, it should multiply fdsec by 100000.0, this fixed the leading zero but the labels still overlap.

commit d47077f3f089dfb90929c7a90d1ed39ab8e94098 added another decimal place of accuracy to Lat/Lon.  But it broke gpsmon.

In the attached screen shot, on the top line, the Lat is 3702.01388, Lon is 7308.01357. 

But look below at both the RMC and GGA sentence displays, the Lat/Lon is 3702.1388, 7308.1357.  Notice no zeros just after the decimal point.

This seems to affect NMEA devices, not other binary GPS devices.
