Dev mode report the wrong startup time starting with Quarkus 1.12

[loicmathieu]

Describe the bug
Starting with 1.12, dev mode report two times startup improvements ! But looking at the timing of the logs it tells a different story :(

There seems to be an issue with the time reporting by the dev mode since Quarkus 1.12

This is the logs from the run of my application, you can clearly see that the application starts in more than 1.8s by comparing the timestamp but the logs reports 0.969s.
