Organizations can opt to use the military time format (24-hour clock) and reduce potential confusion from the 12-hour AM/PM format. This helps provide standardized time representation, global compatibility, and helps ensure accurate time tracking.

To enable for the entire Organization, go to My Organization > Settings > Time Display > Military Time (24-Hour); 
OR
To enable for a specific Warehouse/Location, go to Warehouses > Select a Warehouse > Warehouse Settings > Time Display > Military Time (24-Hour):

Note: when enabled, military time will also display for carriers on the carrier portal.
