Help fixing a missing number in an attribute in pointclouds

Hi, i have a problem where most of a large number of point clouds are missing the first number of the gps_time attribute, so "367091181.0231084" should be "1367091181.0231084". It is always a 1 that is missing at the start.

What would be the best way to go about changing this attribute for every point in every pointcloud?

The context for this is that the point clouds are data from lidar mobile mapping and need to be matched using the gps_time with trajectories in another software.

Any help would be much appreciated.

What data type / format is your source data? txt? csv? las? Do you want to update the source data or do you want to process the data in FME and add the 1 in the data?

My source data is .laz files, so yes it is las files i am working with.

And i would like to update the source data. So i was thinking to process the data in fme and then output a fixed version/copy of the data. But if there is a different/easier way feel free to let me know.

And thanks for your quick answer.
