true time

Being in doubt as to the true time, I am resolved to regard to-morrow, and every seventh day in succession, as the Sabbath.

And is there any considerable difference between solar time, and true time?

My father good-naturedly offered to regulate the halting watch by the true time.

He varies a little, and there is a difference between solar time and true time.

The Aztecs of Mexico, on the contrary, had a solar year, and had made an extraordinary advance in computing the true time.
