A basic query
In a Bourne shell script, I often come across statements involving `sh -c`. I was not able to make out if any reason is there behind that.
example:
echo `sh -c 'date'` killing all server processes

Instead of the above, I can use
echo `date` killing all server processes.
Is there any difference?

man sh says

Code:
OPTIONS
       In addition to the single-character shell  options  documented  in  the
       description  of  the set builtin command, bash interprets the following
       options when it is invoked:

       -c string If the -c option is present,  then  commands  are  read  from
                 string.   If  there  are arguments after the string, they are
                 assigned to the positional parameters, starting with $0.
