Date time format

Standardize date and time format according to PatternFly guidelines

Date

• YYYY-MM-DD - when presented as a numeric value or label
• DD Month YYYY - anywhere else (the month can be shortened to its 3 letter abbreviation if there are any space constraints, eg Jan, Feb...)

Time

• 24 hours (no AM/PM)
• Indicate time zone if time not displayed in user's time zone, or user cannot select their time zone from the UI

Date + Time

• example: 21 Jan 2019, 23:33 UTC
