How do you say 951am in French?

9h51 = neuf heures cinquante-et-un (du matin), or dix heures (du matin) moins neuf minutes. (nuhv urr sank-ahnt-ay-UHN doo ma-TAHN, or deess urr du ma-TAHN mwahn nuhf mee-NOOT) The "du matin" (in the morning) is optional. The French use a 24-hour clock, so 9:51 pm would most likely be stated as 21h51. If you don't specify "du matin" it is assumed.
