Change "Absolute Time" preference when saving to an ASCII (.txt.) file in Signal Express to log a useful timestamp.

Status: New

Currently, there is no way to format a .txt file to log data with a time stamp that includes the current time that the data is being acquired. When creating a "Save to ASCII/LVM" event, the "Time Axis Preference" setting under the File Settings tab has two options: Absolute Time or Relative Time. Relative time works as expected, logging the time starting from 0 seconds until the data acquisition is complete. However, the Absolule Time setting logs the time stamp as time in seconds from some arbitrary point in time, usually the Windows system time in seconds. 

 

This timestamp is essentially useless without a conversion to the actual time. It would be great if the Absolute Time logged the current time in hours:minutes:seconds instead.
