Change CSV logfile Utc format in Excel
Hi all,
I need help to understand how I convert the Utc value in the CSV log file, I use excel for the analysis. A typical format is like below. 45059.344034
Thanks.

Re: Change CSV logfile Utc format in Excel
It is a Microsoft DATE type, so is native to Excel etc.
You can just select the format of the cells in Excel.

Re: Change CSV logfile Utc format in Excel
I use the custom setting d/mm/yyyy h:mm:ss.
It's a custom setting. To get to it: Home tab -> Number -> "More Number Formats" (opens "Format Cells" Box) -> Custom -> then type d/mm/yyyy h:mm:ss (alternatively scroll down the options to d/mm/yyyy h:mm then add ":ss"). Hopefully that is what you want!
If you ever want to convert from UTC to your local time (I do this in a column to the far right so as not to muck up the log file), add your decimal time format to (the number of hours you are different from UTC/24), eg for Sydney outside daylight savings its 45059.344034 + (10/24). If you are 10 hours behind UTC, obviously its 45059.344034 + (-10/24)

Re: Change CSV logfile Utc format in Excel
For those going from Expedition to Unix in Python:
msDate = float(vals["Utc"]) # Expedition's Microsoft DATE like 45059.344034
seconds = int((msDate - 25569) * 86400)
ts = datetime.datetime.utcfromtimestamp(seconds)

Re: Change CSV logfile Utc format in Excel
It is already in the Microsoft time type.
You just need to set the cell text format as above.

It may be some issue with Excel in a mac environment - it definitely works - see image:
