-Note that when running BNC in 'offline' mode, it will use options for file saving, interval, sampling etc. from its configuration file.
+./bnc --file FFMJ.dat --format RTCM_3 --date 2008-10-27 --time 23:12:56
+</p>
+<p>
+Note that it is necessary to define a date and time for the first epoch because RTCM streams do not contain complete time stamps as needed for RINEX. Note further that when running BNC in 'offline' mode, it will use options for file saving, interval, sampling etc. from its configuration file.
