-(1) LM: Change time tag for GLONASS ephemeris from GPS time to GLONASS time (UTC).

+(2) We may also have a date problem in the GLONASS Ephemeris time tag.
     We once saw a wrong date.

+(3) Oscar Colombo describes the following bug in the BRDC and CLK* time tags:
+    "I have found an odd situation concerning the correspondence between the epochs
+    of data in "RTCM3EPH" and of those of the data in "CLK10". 
+    In the file extract below you can see that the "CLK10" corrections to the orbits
+    and clocks are for an epoch close to Greenwich midnight of November 5, 2009
+    (when I was collecting it with BNC 1.7), but the orbits and clocks with the
+    same IODE are the broadcast values for 15:59 hs and 16:00 hs: some 8 hours
+    earlier. So those are midnight corrections to the broadcast orbits and clocks
+    from 8 hours earlier."

+(5) Bandwidth graphics: one column per stream showing the current 
     bandwidth needed. Please consider this as "nice to have" - it's not a must.
     What we have is marked with "Begin new Perlt" and "End new Perlt" in bncwindow.cpp 
     and bncwindow.h. If you don't like it or if its to difficult to implement
     it then: please delete it form the source code.
