/// Description of the time format:

/// Hours ranging from 0 to 23. Can be one or two digits.
hour = { "0" ~ ASCII_DIGIT | "1" ~ ASCII_DIGIT | "2" ~ three_digit }

/// Minutes ranging from 00 to 59. First digit can always be 0, and the second from 0 to 9.
minute = { first_digit ~ ASCII_DIGIT }

/// Seconds ranging from 00 to 59. Similar to minutes, two digits exist.
second = { first_digit ~ ASCII_DIGIT }

/// Indication of AM (before noon) or PM (after noon), in any case and with or without dots.
am_pm = { "AM" | "PM" | "am" | "pm" | "A.M." | "P.M" | "a.m." | "p.m."}

/// First digit for hours, minutes, and seconds. Ranges from 0 to 5.
first_digit = _{ "0" | "1" | "2" | "3" | "4" | "5" }

/// First digit for hours when it's two digits. Ranges from 0 to 2.
three_digit = _{ "0" | "1" | "2" | "3" }

/// Space between time components or absence thereof.
space = _{" " | ""}
