Hi Dennis, There is no method for determining what the date units are for the ticks. The best you could do currently would be to get information about the current viewWindow via the getChartLayoutInterface method and associated methods.
It would be a good idea to provide this info somehow, or at least allow customization of the axis title based on the units used.
