GTA Date / Calendar Mod?

I doubt there is one, but is there a mod that counts the GTA days and can display a date or something? So we can make like a date system for fines, payments, etc? Or is that something thats possible to do?

Pal, Nativedb is your friend.

GET_CLOCK_DAY_OF_WEEK #
// 0xD972E4BD7AEB235F 0x84E4A289
// GetClockDayOfWeek
int GET_CLOCK_DAY_OF_WEEK();
Gets the current day of the week.

GET_CLOCK_MONTH #
// 0xBBC72712E80257A1 0x3C48A3D5
// GetClockMonth
int GET_CLOCK_MONTH();

GET_CLOCK_YEAR #
// 0x961777E64BDAF717 0xB8BECF15
// GetClockYear
int GET_CLOCK_YEAR();

The questions is… why the original game counts the months and the years if there are not events based on time played?
