As usual, he didn't show up on time.

Literal

Example [by-によって] he [topic-は] again on-time [adverbial-どおりに] did-not-appear.

A complaint about lateness. 時間どおりに ('on time, in accordance with the schedule') without は gives a fairly neutral, non-contrastive framing. The ~たためしがない pattern ('there has never been an instance where X') is a strongly negative idiom for habitual failure.
