That's what I always do when technical issues get in the way of me punching in on time, even though I was there.
There were several times I would walk into dispatch and the dispatcher would immediately start babbling about trucks, trailers, meet points and drivers......and I would forget to clock in.
I simply called the feeder clerk and had her change it to the correct time.
There was a point where some feedah drivers were clocking others in.....came close to getting fired.
That stopped real quick.
Never falsify anything.
