Hi,   in the 5.2 documentation (stream topic info ) the date output format is in milliseconds.   But when I launch the same command, the output is of this kind: 2018-02-28T09:21:41.171+0100 The problem is that I don't know if the time is AM or PM.   So, how can I change the date format to get date in milliseconds.           Thank's
