At ServiceNow we have users all over the world, in different time zones, where, strangely enough, they do things like put the day in front of the month. So we understand that there are times when the default date and time format is not going to work for you. The format in which dates and times appear depend on the Date/Time setting. In the UI15 banner frame, click the gear icon 
If you select the Compact list date/time option, the following is not shown with the date in list views:
- year (for date values within the current year)
- seconds
The Compact list date/time option is not available if the Date/Time selection is Time Ago.
Compact list date/time option and time zone:
There is an issue where enabling the Compact list date/time option changes the time zone to Pacific Standard Time. The value is displayed correctly in compact format without the year and seconds, but the time is shown in Pacific Standard Time. If you change the setting back to normal (non-compact) view, the value is once again shown in the user's time zone.
