I'm using babel, datetime & siunitx but I don't see an automatic way to mark and to write time in the french style. It's possible with plain hour with datetime: SI{18}{\hour} -> 18 h. But for hours & minutes, I don't if exists something better than 14~h~27 -> 14 h 27. An idea ?

    For scientific use, I'd expect to see either \SI{14.45}{\hour} or SI{867}{\minute} (assuming you really need that accuracy): mixing units doesn't really work. – Joseph Wright Aug 27 '14 at 10:56

I am not sure of the french style but you can make your own style with datetime:


\twodigit{\THEHOUR}\ h\ %
\twodigit{\THEMINUTE}\ min}



Et  maintenant il est exactement  \formattime{13}{50}{45}.

Ce document a été généré à \currenttime.  


This MWE should produce a ouput like:

Et maintenant il est exactement 13 h 50 min.

Ce document a été généré à 13 h 50 min.

  • Thanks, it works. We can use in french 13 h 50 min or 13 h 50 with …\twodigit{\THEMINUTE}}. Now, my question is, how to print 9 h 05 & not 09 h 05 ? I imagine without \twodigit… I try – Zouib Aug 27 '14 at 12:48
  • Ok, it works. I edit your answer in this way. Last question, impossible to write only two arguments formattime{}{} instead of formattime{}{}{} ? – Zouib Aug 27 '14 at 12:56
  • I propose for using in french texts this form without \twodigit hour & without \minunits : \newtimeformat{frenchtime}{{\THEHOUR}\ h\ \twodigit{\THEMINUTE}} – Zouib Aug 27 '14 at 13:48

    @Zouib, the 3 arguments are mandatory, but you always can make your own command with 2 arguments only: \newcommand\lheure[2]{\formattime{#1}{#2}{00}} – Fran Aug 27 '14 at 21:33
