+(1) 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."

     What we have is marked with "Begin new Perlt" and "End new Perlt" in bncwindow.cpp

     it then: please delete it form the source code.
