log_sum_t() now prints the IP to which the most bytes have been sent in total, rather than the highest amount in one transmission. Also optimized log_sum_d slightly by looking up the numeric representation of the month in a loop-up table rather than with a loop.
Reverted to using date-formatting, resulting in correct date filtering - but rather slow runtime.
