Time, data , and diagnostics
The time, data, and diagnostics are given under the header.
The relationship between Unix Epoch time and the time stamp
The instrument measures time based upon the number of seconds past the Unix
epoch (GMT: Thursday, January 1, 1970 12:00:00 AM). This value is represented in
the
Seconds
column of the data set. You can easily convert the Unix epoch to date
and time using online resources (e.g., https://www.epochconverter.com). If you have
selected a time zone, the Date and Time columns will represent the Unix epoch time
adjusted by an offset for the time zone.
