仅供参考

Answer 1

(?<Time>^(?:0?[1-9]:[0-5]|1(?=[012])\d:[0-5])\d(?:[ap]m)?)

Answer 2

^((([0-9]|([0-1][0-9])|(2[0-3])):([0-9]|([0-5][0-9])):([0-9]|([0-5][0-9])))|((([0-1][0-2])|[0-9]):([0-9]|([0-5][0-9])):([0-9]|([0-5][0-9]))\s[ap]m))$

Answer 4

(?n:^(?=\d)((?<month>(0?[13578])|1[02]|(0?[469]|11)(?!.31)|0
?2(?(.29)(?=.29.((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][
26])|(16|[2468][048]|[3579][26])00))|(?!.3[01])))(?<sep>[-./
])(?<day>0?[1-9]|[12]\d|3[01])\k<sep>(?<year>(1[6-9]|[2-9]\d
)\d{2})(?(?=\x20\d)\x20|$))?(?<time>((0?[1-9]|1[012])(:[0-5]
\d){0,2}(?i:\x20[AP]M))|([01]\d|2[0-3])(:[0-5]\d){1,2})?$)
