Sample To

Selecting the checkbox, you can adjust to any time in the past or future, when sampling should be stopped. If the Sample From checkbox is not selected, it means "start sampling now" and stop when the Sample-To time is reached.

Initially, the spinbutton shows the current time, or what was set previously.

Note: The time-stamp is affected by the setting of the Time-zone. So, make sure the time-zone is set correctly.
