Old 07-09-2010
from second column, do you mean this "[5/Jul/2010:00:59:59" ??

Code:
$ sort -k2 file
abc       [5/Jul/2010:00:59:59    +0000]
xyz    [5/Jul/2010:00:10:00    +0000]
-    [5/Jul/2010:06:10:00    +0000]
-    [5/Jul/2010:06:10:00    +0000]
-    [5/Jul/2010:06:50:00    +0000]
-    [5/Jul/2010:07:10:00    +0000]
-    [5/Jul/2010:08:10:00    +0000]
-    [5/Jul/2010:09:10:00    +0000]
-    [5/Jul/2010:10:00:00    +0000]
-    [5/Jul/2010:10:10:00    +0000]
-    [5/Jul/2010:10:15:00    +0000]
-    [6/Jul/2010:06:10:00    +0000]
-    [6/Jul/2010:07:10:00    +0000]
$

you can provide many options in sort, if this is not the case, please provide the expected output.

If the days of the month in your file were all two digits (padded with 0 if necessary), then this example in the info page of GNU sort can help:

Code:
   * Sort a set of log files, primarily by IPv4 address and secondarily
     by time stamp.  If two lines' primary and secondary keys are
     identical, output the lines in the same order that they were
     input.  The log files contain lines that look like this:

          4.150.156.3 - - [01/Apr/2004:06:31:51 +0000] message 1
          211.24.3.231 - - [24/Apr/2004:20:17:39 +0000] message 2

     Fields are separated by exactly one space.  Sort IPv4 addresses
     lexicographically, e.g., 212.61.52.2 sorts before 212.129.233.201
     because 61 is less than 129.

          sort -s -t ' ' -k 4.9n -k 4.5M -k 4.2n -k 4.14,4.21 file*.log |
          sort -s -t '.' -k 1,1n -k 2,2n -k 3,3n -k 4,4n
