Shell script to append a time for the existing error log file

Hi Guys,

the requirement is like this,
i am having a error log file in this format,

[INFO ][memory ] 4594.493: parallel nursery GC 2594592K->2544691K (2969600K), 30.848 ms

[INFO ][memory ] 4939.716: parallel nursery GC 1339610K->1284920K (2969600K), 41.355 ms

this file will go on displaying all the nursery GC, only 'GC'.

the main aim is that , error log file goes on generating output from weblogic as shown above, we want to take the timespan between two GC's

i.e
[INFO ][memory ] 4642.754-4644.124: GC 2969600K->745408K (2969600K), 1369.515 ms

so i want a script to append time at the end of the line i.e after 'ms'

so will anyone help me out with a script for the above requirement
(atleast suggestions are welcomed)

parport_register_port

PARPORT_REGISTER_POR(9) 				       Parallel Port Devices					   PARPORT_REGISTER_POR(9)

NAME

       parport_register_port - register a parallel port

SYNOPSIS

       struct parport * parport_register_port(unsigned long base, int irq, int dma, struct parport_operations * ops);

ARGUMENTS

       base
	   base I/O address

       irq
	   IRQ line

       dma
	   DMA channel

       ops
	   pointer to the port driver's port operations structure

DESCRIPTION

       When a parallel port (lowlevel) driver finds a port that should be made available to parallel port device drivers, it should call
       parport_register_port. The base, irq, and dma parameters are for the convenience of port drivers, and for ports where they aren't
       meaningful needn't be set to anything special. They can be altered afterwards by adjusting the relevant members of the parport structure
       that is returned and represents the port. They should not be tampered with after calling parport_announce_port, however.

       If there are parallel port device drivers in the system that have registered themselves using parport_register_driver, they are not told
       about the port at this time; that is done by parport_announce_port.

       The ops structure is allocated by the caller, and must not be deallocated before calling parport_remove_port.

       If there is no memory to allocate a new parport structure, this function will return NULL.
