Salut Benoît and Everyone, I used for many moons this: format(Date("10/01/2016"),"mmmm yyyy") and I didn't felt me concerned by that mail......but: format(Date("10/01/2016"),"mmmm yyyy") gives September 2016 now, gave Oktober 2016 before, because Date("10/01/2016") returns 30.09.2016 00:00:00 now (at leased here in Germany). But that is one day lost. I checked that now on Gambas=3.9.90 r8012 but was also on Revision: 8004 -- Amicalement Charlie ------------------------------------------------------------------------------ Developer Access Program for Intel Xeon Phi Processors Access to Intel Xeon Phi processor-based developer platforms.
