Although not the first to do so, ''24'' embraced the concept of [[Real time (media)|real time]]. This idea started when producer Joel Surnow thought of the idea of doing "24 episodes in a season, with each episode lasting an hour". They decided that the idea of real time had to make the show a "race against the clock".<ref name="genesis"/> Each episode takes place over the course of one hour, with time continuing to elapse during the commercial breaks. The exact time is denoted by the digital clock display at the beginning and end of each segment. The protocol is that mundane events, such as travel, sometimes occur during commercial breaks and thus these events are largely unseen.<ref name="Hanks—Jack Back">{{cite news|url=https://www.independent.co.uk/arts-entertainment/tv/features/jacks-back-the-clock-ticks-for-24s-antihero-1027348.html|title=Jack's back: The clock ticks for 24's antihero|last=Hanks|first=Robert|publisher=Independent News & Media Limited|date=November 21, 2008|access-date=July 31, 2009|archive-date=November 6, 2010|archive-url=https://web.archive.org/web/20101106050725/http://www.independent.co.uk/arts-entertainment/tv/features/jacks-back-the-clock-ticks-for-24s-antihero-1027348.html|url-status=live}}</ref> The story time correlates with elapsed viewing time if episodes are broadcast with commercial breaks of set duration inserted at the points prescribed by the episode.<ref name="genesis"/> In line with the depiction of events in real time, ''24'' does not use [[slow motion]] techniques. The series also does not use flashbacks, except once during the first-season finale. Watched continuously without advertisements, each season would run approximately 17 hours.<ref name="Hanks—Jack Back" /> As a result of the timing nature of the series, a number of visual cues were projected onto the screen.

Another idea was the use of [[Multi-dynamic image technique|split screens]], which was born out of the number of phone calls there were, and because of the element of real time, was used to trace parallel adventures of different characters, and aid in the connecting of characters. It was used by producers to point the audience to where to pay attention, as secondary stories often take place outside of the main plot. The idea of using boxes came later, which made shooting more flexible, as the shot could be cropped and reshaped inside the box. It was from here that the idea of using split screens as an artistic element came into the series.<ref name="genesis"/>

A major concept used in the series was the idea of a running clock. This initially came from Joel Surnow, who wanted the audience to always know what time it was in the show's fictional timeline. This was done by an on-screen digital clock that appears before and after commercial breaks, and a smaller clock also appears at other points in the narrative. The time shown is the [[in-universe]] time of the story.<ref name="genesis"/> When the running clock is shown full screen, an alternating pulsating beeping noise (like the kind seen on a time bomb) for each second can usually be heard. On rare occasions, a silent clock is used. This usually follows the death of a major character or an otherwise dramatic event.<ref name="ontheset">{{Cite episode |series=[[On the Record w/ Greta Van Susteren]]|title=On the Set of 24|network=Fox News|airdate=November 1, 2006}}</ref>
