Anyone have any experince with sed or AWK?

im running a BASH script that collect data from MYSQL and echo’s the contents to a tab delimited file, before the data is echo to the file i pipe the output through sed to add formatting.

im having some trouble with trying to add a new line after a certain pattern e.g

Refill Liquid “2010/08/21 12:59” 00:06:00
Refill Liquid “2010/08/21 11:57” 00:06:00
Refill Liquid Im “2010/08/21 11:57” 00:06:00
Preassure fault “2010/08/21 11:57” 00:06:00
Refill Liquid “2010/08/21 14:57” 00:06:00
Refill Liquid Im “2010/08/21 14:57” 00:06:00
Pressure Fault “2010/08/21 14:57” 00:06:00

Fields are tab delimited, im trying to add a line space where the timestamp field is different e.g

Refill Liquid 2010/08/21 12:59 00:06:00

Refill Liquid 2010/08/21 11:57 00:06:00
Refill Liquid Im 2010/08/21 11:57 00:06:00
Preassure fault 2010/08/21 11:57 00:06:00

Refill Liquid 2010/08/21 14:57 00:06:00
Refill Liquid Im 2010/08/21 14:57 00:06:00
Pressure Fault 2010/08/21 14:57 00:06:00

Thanks in advance.
