Re: help regex replacement

sample input 

start_date = '2012-04-29_00:00:00','2012-04-29_00:00:00','2012-04-29_00:00:00',
 end_date   = '2012-05-01_00:00:00','2012-05-01_00:00:00','2012-05-01_00:00:00',

The model would have run on 29th May,  to produce a 48hour forecast to 1sr May 2012.
When I run it on 30th May it should produce a 48hour forecast to 2nd May, i.e. change the entries above so that start_date is 30th and end_date is 2nd May as below.

start_date = '2012-04-30_00:00:00','2012-04-30_00:00:00','2012-04-30_00:00:00',
 end_date   = '2012-05-02_00:00:00','2012-05-02_00:00:00','2012-05-02_00:00:00',

Please provide two data items:
