There is a rather serious bug with the Clocking feature in Org-mode
If you have a Org section that looks like this
* Test
CLOCK: [2019-01-02 Wed 10:06]--[2019-01-02 Wed 11:06] => 1:00
hello
CLOCK: [2019-01-02 Tue 10:06]--[2019-01-02 Tue 11:06] => 1:00
hi
And then you hit C-c C-x C-d you will get a clock total of two hour. If
you change one of them to be a different year - for instance:
* Test
CLOCK: [2019-01-02 Wed 10:06]--[2019-01-02 Wed 11:06] => 1:00
hello
CLOCK: [2018-12-11 Tue 15:10]--[2018-12-11 Tue 16:45] => 1:35
hi
Then the total shows up at just one hour!
Fortunately I noticed this bug before I submitted incorrect timesheet
totals to my employer :)
