Adapting slightly my answer in another thread: 

    my ( $quote, $time ) = m{ \A         # beginning of line
                              (          # begin capture
                               \d+       # digits before decimal
                               \.        # decimal point
                               \d{3}     # three digits after decimal
                              )          # end capture
                              [^,]*      # optional non-comma stuff
                              \s* , \s*  # comma with optional spaces
                              (          # open capture
                               \d\d?     # hours
                               :
                               \d\d      # minutes
                               :
                               \d\d      # seconds
                              )
                            }xms;

Note that this does not require or force $time to have a two-digit hour format. It also won't play well with decimal values that start with a sign.
