So a good quality compass counts as a basic tool? A tall pole that casts a shadow and notes of the time made to correspond to markers placed on the ground at the end of the shadow are all that is needed, no need for a compass. Of course it doesn't work very well here on days like today when the sun is behind heavy clouds. I used to work with people all over the world; discussing time was usually not a problem unless US-ians were involved because very often they didn't know their UTC offset so giving them a UTC time for a meeting wasn't useful. :-)
