Of all the recent threads I read on the subject recently, I did not see
the method I use, which is quite simple.   Obtain the sunrise/sunset
times from the newspaper, radio/tv weather reports, or even Geoclock for
the day you want to check true north.  1.  Convert the sunset time to
24hr format by adding 12 hours.    2. Add the sunrise and sunset times. ,
3. Divide by 2 to obtain the time of your local meridan crossing.    The
sun is at its highest point and cast a true north shadow at this time.  
If the total hours are an odd number such as 25,  subtract 1 hr and add
60 mins to mins side.  If total hours are odd and minutes total more than
60, subtract 60 and add 1 to hours side.
