By default, screenshot files are saved with names like this:

The date format is great, but the time format annoys me because it doesn't sort automatically. Is there any way to change the format to:

It's using the system's standard date/time display format which you can customise in the 'Formats' tab in System Preferences → Language&Text

Or, it might be quicker to just change the time display of the clock to 24-hours mode: System Preferences → Date & Time

(I have OS X 10.7.5, so it may be organised/worded slightly differently in newer OS X versions.)

  • System Preferences → Date & Time , click Open Language & Region..., check 24-Hour Time. Screenshot was saved in 24-hours format. Thanks. – kangbu Aug 3 '18 at 8:02

I've found the most minimal solution (on macOS 10.14.3) to be:

System PreferencesLanguage & Region, then click Advanced..., choose the Times tab and for the Medium format click the hour dropdown and switch it from 1-12 to 00-23 and delete the AM/PM element:
