^([012][0-9])-(Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)-\d\d\d\d [012]\d:[0-6]\d:[0-6]\d\.\d\d\d

Explanation:解释：

^                   start of a line
([0123][0-9])       00 to 39 (for simplicity, instead of 00 to 31)
-                   a hyphen
(Jan|Feb|Mar...)    the month
-                   another hyphen
\d\d\d\d            0000 to 9999
[012]\d             00 to 29 (for simplicity, instead of 00 to 24)
:                   a colon
[0-6]\d             00 to 69 (for simplicity, instead of 00 to 60)
:                   another colon
[0-6]\d             00 to 69 (for simplicity, instead of 00 to 60)
\.                  a dot
\d\d\d              three digits
