- // the problem: there is no way to know what do these format

- // the solution: use a hack and still use strftime(): first
- // find the YEAR which is a year in the strftime() range (1970
- // - 2038) whose Jan 1 falls on the same week day as the Jan 1
- // of the real year. Then make a copy of the format and
- // replace all occurrences of YEAR in it with some unique
- // string not appearing anywhere else in it, then use
- // strftime() to format the date in year YEAR and then replace
- // YEAR back by the real year and the unique replacement
- // string back with YEAR. Notice that "all occurrences of YEAR"
- // means all occurrences of 4 digit as well as 2 digit form!
- //
- // the bugs: we assume that neither of %c nor %x contains any
- // fields which may change between the YEAR and real year. For
- // example, the week number (%U, %W) and the day number (%j)
- // will change if one of these years is leap and the other one
- // is not!
- {
- // find the YEAR: normally, for any year X, Jan 1 of the
- // year X + 28 is the same weekday as Jan 1 of X (because
- // the weekday advances by 1 for each normal X and by 2
- // for each leap X, hence by 5 every 4 years or by 35
- // which is 0 mod 7 every 28 years) but this rule breaks
