13 Time period selector

Overview

The Time period selector allows to select often required periods with one mouse click. It can be expanded or collapsed by clicking the Time period tab in the top right corner.

Options such as Today, This week, etc., display the whole period, including the hours/days in the future. Options such as Today so far, This week so far, etc., display only the hours passed.

Once a period is selected, it can be moved back and forth in time by clicking the arrow buttons. The Zoom out button allows to zoom out the period by 50% in each direction.

For graphs, selecting the displayed time period is also possible by highlighting an area in the graph with the left mouse button. Once you release the left mouse button, the graph will zoom into the highlighted area. Zooming out is also possible by double-clicking in the graph.

The From/To fields display the selected period in either absolute time syntax (in format Y-m-d H:i:s) or relative time syntax. A relative time period can contain one or several mathematical operations (- or +), for example, now-1d or now-1d-2h+5m.

The following relative time abbreviations are supported:

  • now
  • s (seconds)
  • m (minutes)
  • h (hours)
  • d (days)
  • w (weeks)
  • M (months)
  • y (years)

Precision is supported in the Time period selector (for example, /M in now-1d/M). Details of precision:

Precision From To
m Y-m-d H:m:00 Y-m-d H:m:59
h Y-m-d H:00:00 Y-m-d H:59:59
d Y-m-d 00:00:00 Y-m-d 23:59:59
w Monday of the week 00:00:00 Sunday of the week 23:59:59
M First day of the month 00:00:00 Last day of the month 23:59:59
y 1st of January of the year 00:00:00 31st of December of the year 23:59:59

It is also possible to select a time period using the Date picker. To open it, click the calendar icon next to the From/To fields.

Within the date picker, you can navigate between year/month/date using Tab, Shift+Tab, and keyboard arrow buttons. Pressing Enter confirms the selection.
