Convert Date to 24 hr format

Content

Hi ,

I want to convert into 24 hr format  in SOASuite XSLT ,  but i am getting time in 12hr format.

Below is the function ,

I tried below ,the sample datetime but still i am not getting time in 24 hrs format .Does this format function work ? For 24 hrs, it shouldbe '[H01]' right ?
xp20:format-dateTime(xs:dateTime('2019-09-11T10:16:31.943+05:30'), '[D01]/[M01]/[Y001] [H01]:[m01]')
