An off-hand search in the codebase shows a mix of time display formats, including some with subtle differences. E.g.,

• Sep 3, 2021 at 9:14 pm (active statements, active transactions)
• Sep 3, 2021 at 9:14 PM (jobs table retention time)
• Sep 03, 2021 at 9:14 PM (databases table and details)
• September 3, 2021 at 9:14 pm (statement diagnostics)

Others are more different:

• 21:14:33 on Sep 3rd, 2021 (metrics page graph hover)
• Sep 03, 2021 21:14 (statement details last execution time)

Related to #81077, it might be helpful to standardize this, including by having one shared string variable for the display format (or having all possible formats as variables in one file).
