I noticed under settings > change units>time .... there are two options which are Local (this machine) abd the other is Universal (UTC) ..... I assumed that would alter the LOG once the flight was completed to local time (if set to this machine) or Zulu if set to UTC .... I just tried it  and no, it still shows times in Zulu. 

Any idea what this option actually does as my preference woukd be for the completed flight log to be in local time  GMT or British summer time

Thanks in advance
