/* NOTE: The date[20] field is another historical embarrasment. The
format is, exactly:

	"dd Mon yy  hh:mm:ss"

where dd, yy, hh, mm, and ss are two digit numbers, zero filled where
necessary, and Mon is the first three letters of the month, in English,
lower case with the first letter upper case. There are TWO SPACES between
yy and hh.

This format is very important (this is the embarrasing part) because
Fido since v3 has done arithmetic on the string itself. Please preserve this
EXACT FORMAT if you wish things like RENUM and PURGE to work correctly.
