After creating an instant of clock (by Do it) The number of month in the resulting comment (java.util.GregorianCalendar[ ...) is
always the real number minus 1. By example the month january is indicated by MONTH=0.
If this is an error in the rendering of the comment than it does not matter but maybe it points to an underlying more severe error?
All the other parameters: YEAR, DAY_OF_MONTH, HOUR_OF_DAY, MINUTE, SECOND give the right number, only MONTH gives the number-1
This is how "10/19/2020 12:05:30" looks like
