It is not uncommon for a lidar point cloud to have time tags in pure GPS Time, which

is the number of seconds since $1980$ January $0600$:$00$ UTC. Convert the following

GPS Times to GPS Times of Week or vice versa. For all GPS Times of Week, assume

we are in the current era in which two week$-$rollovers have occurred.

a$.1276259714$

b$.$ Week $147,339760$ seconds
