You expect the meeting to be held in the middle of the night? 'The meeting is today at 2!' is unambiguous in most cases (certainly with a 9-to-5 job). In many locales where the 24 hour clock is used, people refer to the hours after noon as one, two, three o'clock etc. Then when you write it down somewhere two o'clock becomes 14:00.
