Chronemics is greatly influenced by cultures and an individual's experiences. While some cultures value a more monochronic view of time systems (using time precisely and segmenting it into scheduled and arranged units), other cultures value a polychronic view of time systems (doing several things at once and seeing time as fluid instead of precise). Chronemics also includes the biological settings that individuals are programmed with regarding time.

If we consider just the way our internal body clocks influence our public speaking capabilities regarding time, the following could be included:

• A speaker has a time of day when they are at their mental prime. Let's say that a speaker's best time of day to engage in intellectual discourse is 10:00 a.m. If they must give a speech at 6:00 a.m., they may falter in content. A speaker would need to recognize their own public speaking weaknesses outside of their prime hours and attempt to compensate (waking earlier, having additional notes, drinking an extra cup of coffee, etc.).
• It's possible that the audience is similar enough that overall it has an optimal time for listening to a speaker. For example, it has been well-documented that the teenage brain does not operate best early in the morning. If a speaker was asked to deliver content to a group of 15-year-olds at 7:30 a.m., they would need to acknowledge the chronemic discord and structure their speech in a way that would engage and maintain the attention of an audience whose body clocks are not aligned to the time of their speech.
• Most audiences have a body clock that is programmed for intellectual rest on weekends. Asking an audience to attend a presentation on a Saturday afternoon will likely cause higher than typical distraction rates among audience members. A speaker who is asked to present to an audience on the weekend should consider ways to actively engage an audience who may not be operating at their mental peak.
