View source for How to record the time at which users viewed an intervention page or completed a particular section of the intervention

The logic command <code>currenttime()</code> is used to record the time.

===Example 1===
<code>show session1_page10
savevalue(username, "session1time", currenttime())
show session1_endpage</code>

The above example will save the current time (in seconds) when users click on the next button on page session1_page10.

N.B. If users see '''session1_endpage''' more than once, '''session1time''' will be saved and overwritten each time they see it. If you want to only save the time the first time '''session1_endpage''' is seen, you can add a line of hasseen '''logic''' as shown in Example 2 below.

===Example 2===
<code>savevalue(username, "session1time", currenttime()) if (not(hasseen (username, "session1_endpage")))</code>

This logic will only save '''session1time''' if the page '''session1_endpage''' has not been seen by that user before.
