Is there a reason you are encoding the date as the integer 20,100,103 instead of the number of seconds past the epoch or as a julian date? The reason I ask is that there are oodles of Date, Date/Time, and Julian Date classes out there for you to steal, er, utilize. But if you need the date to be in the aforementioned integer, you will have to manage how you add and subtract dates. Subtracting 1 will not work as intended:
20010102
20010101
20010099
20010098
Nor will adding 1:
20010227
20010228
20010229
20010230

If you want to extract the parts of the date, then:
Code:
int day   = air_date % 100;
int month = ( air_date / 100 ) % 100;
int year  = air_date / 10000;

NAME
stMktime, stWriteTime - date and time handling SYNOPSIS
#include <config.h> #include <sttk.h.h> time_tstMktime (char *string); char*stWriteTime (time_t date); DESCRIPTION
stMktime scans the given string and tries to read a date and time from it. It understands various formats of date strings. The following is a list of all valid formats, optional parts in brackets. [Tue] Jan 5[,] [19]93 This includes the standard asctime(3) format. Jan 5 With no year given, the year defaults to the current year. [19]93/01/05 This notation requires month and day represented by exactly two digits. 5.1.[19]93 This is the usual German notation. 5.1. German notation referencing the current year. A certain time, given together with the date must always have the following form. hours:minutes[:seconds] Each of the fields must be an integer value within the proper range (hours: 0-23, minutes and seconds: 0-59). Values below 10 may be written as one digit numbers. The time value may be placed anywhere in the date string: at the beginning, at the end, or somewhere in the middle. Any amount of white- space may be given between a field of the time value and the separating colon. The time is always considered to be local time. stWriteTime generates a time string similar to asctime(3) from its date argument. SEE ALSO
asctime(3) BUGS
Time Zone Names within the time string (like `MET') are not handled properly. In most cases they will cause a failure. sttk-1.7 Thu Jun 24 17:43:35 1993 sttime(3)
