If the string is allways the same structure, then you can do something like this:

Code:
string1='a.sh start time is Fri Jan  9 17:17:33 CST 2015';
string1=${string1%* CST 2015}
string1=${string1##* }

string2='a.sh start time is Fri Jan  9 17:17:33 CST 2015';
string2=${string2%* CST 2015}
string2=${string2##* }

clear && echo $string1 && echo "" && echo $string2

NAME
times - shell built-in function to report time usages of the current shell SYNOPSIS
sh times ksh times DESCRIPTION
sh Print the accumulated user and system times for processes run from the shell. ksh Print the accumulated user and system times for the shell and for processes run from the shell. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file name genera- tion are not performed. ATTRIBUTES
