Hard to believe in 2018 bobsled doesn't use a timing system that goes to the thousandth of a second.
I think they do. The problem is that the sleds don't start at the same time. So anything measured to the thousandths of the second is off by +/- one or two thousandths at the beginning and +/- one thousandths at the end. That's true for both sleds, so it's only accurate to several thousandths. That's almost a hundredth.
If you really want relative accuracy to the thousandth, you have to measure time to the ten-thousandth, which is harder to do.
In T&F, everyone starts at the same time and finishes at the same time, so you don't have to look at the differences between two sets of measurements, you don't even have to look at the difference between two measurements, you just have to look at the finish line photo. You can't have a finish line photo in bobsled.
On top of which, the conditions are different enough between runs that it really doesn't make sense to measure time to the thousandth or ten-thousandth of a second.
