Change MTR logfile timestamps

A tool for orienteering event organisers to modify time stamps in log files generated by emit's MTR4 card reader.

This tool is made for orienteering organisers who use emit for time keeping and need to change the readout timestamps of all emit cards in a log file.

If your MTR runs behind real world clock time, you need to add time using this script. If your MTR runs ahead of real world clock time, you need to subtract time.

The problem

When I organise orienteering events without a fixed start time for each competitor using emit and the MTR4 for card readouts, I need the correct clock time on the MTR4. If the clock is wrong on the MTR4, all runners will have wrong start and finish times. Their total time will be correct, but incorrect start and finish times will make problems for software such as Livelox which uses start times and split times to determine when a participant punches each control.

About this tool

This tool can alter the timestamps of all read emit cards in a log file. Usually I generate the MTR log file using tTime and its MTR module.
