Sorting records in unix

On Unix: I have a text file that has records that I need to sort in ascending order of date and time. I have looked at the sort command and couldn't get it to work for me. Could someone please help me with this? Or point me in the right direction?

{
  DateAndTime : "2010-08-27-11.42.43.082-0400",
  TestString:"12开发者_开发知识库3",
   TestData : {
    { field0 : "1234" },
    { field1 : "5678" }
              }
}

{
  DateAndTime : "2010-08-28-11.43.43.082-0400",
  TestString:"123",
   TestData : {
    { field0 : "1234" },
    { field1 : "5678" }
               }
}

Reading file line by line using awk or read will help.

cat test | while read field1 $field2 ; do sorting with field1 and prev_field1; prev_field1=field1 ; done
