[Uptime] Uptime not using standard Kibana date/time format in places

[paulb-elastic]

Although the standard Kibana date/time format is used in some places, there are a number of places it is not.

For example, when the standard Kibana format is defined as:

it is shown on the check details view screenshot:

However, not elsewhere:

In addition, it is quite likely that the main date format is too granular (for example as seen above, these are millisecond granularity, but that's not useful when looking at the test result, which should be to second granularity).

As there is no scaled date format that includes this level of precision, the suggestion is to use a combination of scaled date formats, P1DT + PT1S in those places.

• Use PT1S or P1DT+PT1S (using the same logic as now, depending on how recent the test is) here:
  • Uptime Overview Monitor List > Collapsed summary
  • Uptime Overview Monitor List > Expanded view
• Use P1DT+PT1S here:
  • Monitor History list
• Use the standard Scaled date format on the Pings over time charts (x-axis)
  • On the Overview page
  • On the Monitor History page
