I have a file which has the data in the following format: Dec-13-09:46:45 21.4 +4.76442190E-01 8.135530E-06 1.553691E+00 Dec-13-09:47:12 21.4 +4.76439120E-01 8.135839E-06 1.553726E+00 Dec-13-09:47:39 21.4 +4.76427260E-01 8.136261E-06 1.553853E+00 . . the first field is a timestamp, I'd like to replace it with the time in seconds starting from the first one like this: 0 21.4 +4.76442190E-01 8.135530E-06 1.553691E+00 27 21.4 +4.76439120E-01 8.135839E-06 1.553726E+00 54 21.4 +4.76427260E-01 8.136261E-06 1.553853E+00
