Bug unable to read a parameter

All,

on command prompt when i am testing I am able to get the value of 'msgtime' parameter but in the script I get a space value for it . Please help ..

following is the code snippet -

Code:
grep "Component Manager stopped" msgtime.txt | while read line
                                                 do
                                                     awk '{ print $2}' | sed 's/://g' | read msgtime
                             echo $msgtime  # does not display msgtime instead gives space
                                                done

msgtime.txt looks like this -

Code:
pe.txt.2012-03-28:2012/03/28 11:51:02 [RMI TCP Connection(147)-10.87.130.42] INFO  filenet.vw.ComponentIntegrator  Component Manager stopped.

Please help.

NAME
fence_sanbox2 - Fence agent for QLogic SANBox2 FC switches DESCRIPTION
fence_sanbox2 is an I/O Fencing agent which can be used with QLogic SANBox2 FC switches. It logs into a SANBox2 switch via telnet and dis- ables a specified port. Disabling the port which a machine is connected to effectively fences that machine. Lengthy telnet connections to the switch should be avoided while a GFS cluster is running because the connection will block any necessary fencing actions. fence_sanbox2 accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_sanbox2 can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
