Found it !!

When inside my town with a building under construction, I look at the javascript (using Firebug for Firefox) and at the end of it the start and end dates are shown.

For example, I am upgrading my stonemason from level 28 to level 29 and it shows :

The difference is 97'711 seconds, exactly what the formula gives (i.e. 1D:3h:8m:31sec)

EDIT: here is how you can do it easily:

1- Once in the town with the building under construction, make sure to reload the "town view".

2- Right click on the page and select "show source code"

3- Go approx line 700 or search "endUpgradeTime" in the page (shortcut "Ctrl+F" on my Windows PC)

4- The difference between the endUpgradeTime and the startUpgradeTime should be the actual building time, in seconds.

I hope it will be helpful ;)
