Subject: [PATCH] test(harness): make formatClockTime tests locale independent

The date assertions matched the English month abbreviation, so the suite failed on any machine whose system locale is not English (for example tr-TR renders Jul as Tem). formatClockTime deliberately formats in the user's locale, so the source is correct and the test was over-specified.

Assert the shape instead: the dated form is the same-day form with a date and a comma prepended. Verified across de-DE, ja-JP, tr-TR and en-GB in three timezones.
