I need some help with creating a custom cell format for the following format:
hours, minutes, seconds, and milliseconds (hh:mm:ss.mmm)
I changed the format of the column that stores the "IRIG" (Inter Range Instrumentation Group) format to "General"... initially, when typing in the value, it holds it in the proper format. Once I click on the cell, e.g. copy it, then click on the "green check (formula bar), the format changes... sometimes to decimals, othertimes to regular date format.
Does anyone know how to include "milli-seconds" in a date-time-stamp?
