The sentence presents punctuality as part of Bond’s professional discipline. Although he has had relatively little sleep, he still arrives at headquarters at the expected time. Fleming uses the contrast between the late night and the precise arrival to emphasise routine, self-control and reliability.

The detail also helps distinguish personal circumstances from professional obligations. Bond does not allow tiredness or the previous evening’s activities to alter his conduct at work. The emphasis is not on exceptional heroism, but on an ordinary standard being maintained despite inconvenience.

More broadly, the quotation reflects the importance of dependable habits in demanding professions. Punctuality becomes a small but visible sign of responsibility: the individual is expected to meet established obligations regardless of private discomfort. In this sense, the passage presents discipline as something demonstrated through consistent behaviour rather than occasional dramatic action.
