Thank you for the update. I will explore those. I am trying to figure out what do about time. I was just informed that my date and time is not being provided as some form of serial number in integer format. Instead it is going to be a column with the date, likely in day of year, while the time column is going to be hh:mm:ss.ssss. It should match the IRIG MIL-1553 Chapter 10 format from the range commander's tools. I guess I could request that they provide the RTC data, which is millisec since on time and then just use the traditional date time for labeling.
