Instead of assuming everyone knows whatever COH Standard Time is, it would be good to post the time to include the Timezone as a reference. Or, convert to UTC/Zulu time and let everyone calculate it themselves...but even that includes a TZ reference or offset.
Sorry, I do a lot of work shaping data logs and including TZ offsets/references and/or using something that doesn't move, like UTC, is just in my wheelhouse and my personal obsession. Too many years jousting that knight of vagueness.
