Different timezone for page optimization and page caching

My site runs in Australia, which is GMT+10. After clearing all caches, this is what I see at the bottom of pages:

```

```

The difference between the timestamps is precisely 10 hours. Personally, I prefer to see the local time, but whichever timezone is used, it should be both consistent and clear. Also, optimization doesn't specify the version, and used "@", instead of "on".

So we should see one of the following:

```

```

OR

```

```

Start by locating the code that writes the “Page optimized” and “Page generated” HTML comments, then inspect how each timestamp and version is produced. Compare their timezone and formatting behavior with the examples in the issue; done means both comments use the same clearly labeled timezone, wording, and plugin version.
