Replace days_to_seconds function with macro

This function was a [huge] waste of processing power and complexity.
Replaced with a macro for easier readability of code, since 86400 (the
number of seconds in 24 hours) isn't immediately obvious what it is. Now
it is referenced by the macro SECONDS_IN_DAY.
