Actually this error is unrelated. It has been there since Calc was added = to the Emacs tree in 2001: the number of days from the Calc epoch to = start of Unix time was incorrectly given as 719164 but the correct = number was 719162 before the change in Calc epoch in 2012, and since = then it should be 719163. The "t U" command was fixed in 2015 (e368697ce36) along with the = documentation. The attached patch fixes the remaining uses of the wrong = constant, in the date parsing and formatting code. Vincent, is this = patch helpful? --Apple-Mail=_1AE4D75C-4940-4083-9699-C6077DFD5AF7 Content-Disposition: attachment; filename=0001-Calc-fix-formatting-and-parsing-Unix-time-bug-43759.patch

Actually this error is unrelated. It has been there since Calc was added to= the Emacs tree in 2001: the number of days from the Calc epoch to start of= Unix time was incorrectly given as 719164 but the correct number was 71916= 2 before the change in Calc epoch in 2012, and since then it should be 719163.

The "t U" command was fixed in 2015 (e368697ce36) along with the = documentation. The attached patch fixes the remaining uses of the wrong con= stant, in the date parsing and formatting code. Vincent, is this patch help= ful?
