Analyzer for log files of time stations
This tool uses radio_datetime_utils and per-station libraries to analyze log files of these stations.

Usage
The program takes two parameters:
- the station name of the file to analyze (as argument to the -s option)
- the name of the file to analyze (as argument to the -f option)
The -u option shows the decoded date in time in UTC instead of local time. The "summer" and "winter" indicators are replaced by "UTC", information on DST transitions is still shown.
The -h option provides a short help message.
Currently supported stations are dcf77 and msf.
DCF77 is the German time station at 77.5 kHz, and MSF is the British time station at 60 kHz.
Wikipedia has more information on both stations.
Input files
All input files in plain text, with generally one line per minute, unless reception errors occur in which case false minute markers might be received. The analyzer returns the date, time, day-of-week, and DST (daylight saving time) status of each analyzed minute. Parity and temporal errors are also reported. Some information is only available for certain transmitters:
-
DCF77:
- call bit for technicians (does not affect the received data)
- announcement of leap second
- information meant for third parties
-
MSF:
- DUT1 value (difference between UT1 and UTC in tenths of seconds)
File format for DCF77
There are five characters for DCF77 log files. All other characters are discarded.
- '0' denotes a 0 bit
- '1' denotes a 1 bit
- '_' denotes a bit which could not be properly decoded
- '*' resets the internal decoder state, it should generally not be followed by a newline
- newline denotes a new minute
File format for MSF
There are seven characters for MSF log files. All other characters are discarded.
- '0' denotes a 0,0 bit pair
- '1' denotes a 1,0 bit pair
- '2' denotes a 0,1 bit pair (only occurs in bit 1-16)
- '3' denotes a 1,1 bit pair (only occurs in bit 53-58)
- '4' denotes the 500 ms new-minute marker
- '_' denotes a bit which could not be properly decoded
- '*' resets the internal decoder state
- (the newline is just a comment here)
