-t Change the access and modification times to the specified time.
The argument should be in the form ``[[CC]YY]MMDDhhmm[.SS]''
where each pair of letters represents the following:
CC The first digits of the year (the century).
YY The second two digits of the year. If ``YY'' is
specified, but ``CC'' is not, a value for ``YY''
between 69 and 99 results in a ``CC'' value of 19.
Otherwise, a ``CC'' value of 20 is used.
MM The month of the year, from 1 to 12.
DD the day of the month, from 1 to 31.
hh The hour of the day, from 0 to 23.
mm The minute of the hour, from 0 to 59.
SS The second of the minute, from 0 to 61.
If the ``CC'' and ``YY'' letter pairs are not specified, the val-
ues default to the current year. If the ``SS'' letter pair is
not specified, the value defaults to 0.
