When time is enabled for any of the layers in your map, the Time tab appears along the top of the display providing additional settings to configure the behavior of the time slider and its controls. The settings are organized into groups along the Time tab for Current Time, Step, Playback, and Full Extent.
Use these settings to configure the time in the map for the visible time span.
Start Time and End Time
Set the map time to a specific date and time. Type directly in the text box or click the date-time picker to choose year, month, date, and time.
The visible time span for the map, which is the difference between the start and end times. The span remains constant as you step through the time slider.
Disable/Enable the Start or End Time
Use the button next to the date-time picker to Disable or Enable the corresponding time slider control. When start time is disabled, the time in the map is represented by all time before the end time. When end time is disabled, the map time is represented as all time after the start time. If both are disabled, this is equivalent to disabling time or showing all time.
Lock/Unlock the Start or End Time
Use this option to lock the start or end time at a specific time. When the control is locked, it cannot be moved by dragging the control. In addition, during playback, the control will not move.
Exclude Start / Include Start
You can set the visible time span to include values greater than but not including the start time, or include values greater than or equal to the start time.
Exclude End / Include End
You can set the visible time span to include values less than but not including the end time, or include values less than or equal to the end time.
The Step group provides options to set the amount of time to move when using the Next or Previous step commands, or during playback.
Number of Steps
Use this option to set the step to a relative amount of time. The slider is divided into the specified number of steps as you move through the time extent.
Use this option to set the step to an explicit amount of time. It is defined using a value (.5, 1, 100, and so on) and a time unit (Seconds, Months, Years, and so on). The time unit will be locked if Time Snapping is enabled.
Turn on time snapping and configure the time unit, such as days or years, as the interval at which snapping occurs.
Enable automatic snapping of the map's current time to a standard time unit, such as days or years, for easier navigation through time. When first enabled, the map time will be updated to comply.
Time Snap Interval
The map's current time extent will automatically snap to this time unit.
The Playback options are used to configure the behavior of the time slider when you click the Play button.
Play All Steps
Autoplay all steps from the current position of the slider thumbs to the edge of the slider extent. Pause will stop playing and leave the slider controls in the last played position.
Step Forward / Step Back
Step the time slider Start and End thumbs forward or backward according to the current time settings.
Set the relative speed of the visualization using this slider. This option adjusts the amount of time to pause at each time step before moving to the next step.
Set whether playback begins by moving forward or backward in time.
When the slider thumbs get to the end of the slider bar, by default, the controls stop. You can optionally set it to repeat and loop playback in the same direction.
When the slider thumbs get to the end of the slider bar, playback will continue in the opposite direction and stop.
The Full Extent group defines the time extent to set the slider bar when you click the Full Extent button .
All time-enabled data
Define the full time extent to the extent of all temporal layers in the map. This is the default option.
All visible time-enabled data
Define the full time extent to the extent of all temporal layers that are visible in the map. This time extent updates as layer visibility changes.
Define the full time extent to the extent defined in the start time and end time edit controls. If you edit either of the values in these controls, the option is automatically set to user defined.
Every time-aware layer in the map shows in the drop-down list. Selecting a layer defines the full time extent to the extent of that layer.
Set the time slider to show the defined full extent.
Unlock the extent of the slider so it can be modified interactively.
Use this group to define the time reference of the map time.
Set the time zone used by the map. Content from time-aware layers in different time zones will be displayed in accordance with the map's time zone. If the map's time zone is set to None then all time-aware layers will display using their raw values, as though they have no knowledge of a time zone.
Adjust For Daylight Savings
Specify whether the time reference should account for daylight savings time and adjust the time according to the rules of daylight savings for the given date.
