Removed use of struct tm and fixed extra line highlight bug

[AndreaEgan06]

The math in the long if condition was refactored as it was causing the bug.

time(0) returns the number of seconds since 01/01/1970 as a time_t, which at least for Macs is just a typedef for long

I also watched the most recent stream and have a better suggestion:

Rely on ctime() and simply parse its output. Starting from offset 11, an exact ASCII string representation of the local time is returned (though you only need the first 8 characters [11,19) to determine the digit). Furthermore, since ord(':') == ord('9') + 1, you can simply subtract by '0' to get the zero-based index of the character, even if it's a colon.

Example code:

time_t t = time(0);
char* a = ctime(&t) + 11;
for (int i = 0; i < 8; ++i) {
  int index = a[i];
  /* do what you need to with index */
}

Here's my playground in cling, a C++ interpreter:

****************** CLING ******************
* Type C++ code and press enter to run it *
*             Type .q to exit             *
*******************************************
[cling]$ #include <time.h>
[cling]$ time_t t = time(0);
[cling]$ char* a = ctime(&t);
[cling]$ a
(char *) "Sat Jun 15 18:41:17 2024
"
[cling]$ a + 11
(char *) "18:41:17 2024
"
[cling]$ a[19]=0;
[cling]$ a + 11
(char *) "18:41:17"
