The Qualtrics APIs use date and time values which follow the ISO 8601 standard. Each value represents a specific point in time.
In general, although the ISO 8601 standard specifies many different date and time formats, the typical date and time value specifies the date as YYYY-MM-DD (where YYYY indicates a four-digit year, MM is a two-digit month, and DD is the two-digit day of the month) followed by the character "T" and then the time as hh:mm:ss (where hh is a two-digit hour in military time format [00-23, no AM or PM], mm is the two-digit minutes past the hour, and ss is the two-digit seconds) followed by the character Z which indicates UTC. Instead of Z, a time zone offset from UTC can be indicated as plus (+) or minus (-) followed by HH:mm.
The following shows examples of ISO 8601 dates and times:
- 2016-04-01T07:31:43Z represents April 1, 2016 at 7:31:43 AM UTC.
- 2017-02-07T14:02:11-08:00 represents February 7, 2017 at 2:02:11 PM in the PST time zone (UTC minus 8 hours).
All date and time values returned by the APIs are expressed in UTC unless the API allows you to return values in local time. For example, Create Response Export has the useLocalTime parameter that, if set to true, causes the times in the responses to be expressed in the time zone set in the admin user interface.
