I'm currently developing a dashboard for monitoring some objects that my corporation designs and manipulates. Those objects come with a date and time, that I translate from a cron table. In standard CRON, hours are expressed within the range 0-23 so it'd be great if I could express the time in a 24 hours format, that'd relieve me from the need of translating into AM/PM format.
I really would like to make my website user-friendly for everyone: I don't mind having to write more code, but I know that in the country I'm working in, people aren't very familiar with the AM/PM format and my coworkers are likely to get confused between times in the morning and past noon. As those latter represent the main pool of users for my website, I'd like to think a format that suit everyone, them and the English-speaking users.
Are English-speaking people familiar with the 24 hours format for expressing times?
