Thank you all. @Bryan: True. I'm sure it's not specific to spectra, but I knew anyone that has worked with a date from spectra would recognize what I meant by the example. Didn't know what else to call it.
@Ray: No access to spectra code. Just the legacy data. @Kym: Good catch, it does seem to be the percentage of the day. @Morgan: Thank you! Numberformat with that mask is the winner. Below are results and test code. I think maybe the milliseconds are what's throwing it off but it's more than close enough for my needs.
