Step 5 - Display Date and Time using UTC Offset (optional)
Upon export to CSV format, all data records are
automatically corrected for receiver clock drift by the
Fathom software. Fathom uses the difference between the
receiver's clock and the UTC time calculated from your PC
clock at offload to calculate corrected times for each record
in the receiver log. If receiver clock times were also
adjusted during deployment (for example, using an external
device to periodically send time corrections to the receiver
through a cabled connection), then these adjustments are
also used to calculate corrected times for records in the
receiver log.
The exported CSV file includes:
l
a field containing the original uncorrected date and
time for each data point (Device Time (UTC) and
l
a field containing the corrected date and times
(Time).
The corrected field will be provided in UTC format unless
an offset is specified under Time Offset in Hours . The
selected offset is displayed in the column header of the
generated CSV file.
To display drift-adjusted (corrected) date and time
according to a specific UTC Offset , in the Time Offset in
Hours field, type in a value for the offset.
