That is neither incorrect nor inconsistent. The numbering scheme is
from the UNIX struct tm. Since people would want to print the date
in human-readable format, the month and day-of-week values are chosen
so as to be used as indices into string arrays (i.e., char **) for the
names. So month[0] = "Jan" and dow[0] = "Sun". The day-of-month,
OTOH, isn't needed as an index but would be printed directly;
therefore the first of the month is 1.
