This looks a lot like (overlapping) method time stamps.

Here, I tried to disentangle them:

Most looks like 8 byte method name and 8 byte stamp.
Some are differently broken, tho (see empty areas)
Also, the method part seems to come from source code, it includes ^ and ".

Hope that helps.

Best regards
