Convert Timestamp in text to Serial Date-Time

Hi,
I have a data file where the timestamp is in the style of:
2016-10-11 07:01:23.375-500

which is yyyy-mm-dd hh-mm-ss-000 then time conversion from UTC

What i need to do is convert these timestamps from the above format to a the Serial Date format (i.e 42,654.2920446 )

now.. if really would be allowed to push my luck, i would like this format specified to 20 decimal places, AND use the "-500" to convert back to UTC

any help would be greatly appreciated.

Forgive my ignorance, but what is this Serial Data format? Or do you mean Serial Date format? Googling the former comes up with nothing appropriate; googling the latter comes up with references to Excel and Matlab.

My best guess is you want to convert to the number of days since a certain date. What is that date?

Thanks Andrew.
I did indeed mean serial date (i've just edited my original question).
What I'm looking for is the date used in excel.

so really converting any of those data/timestamp strings in my original file to the equivalent excel timestamp.

regards

i have code that converts from the data format mentioned into epoch.

Code:
 awk -F, '{"date +%s -d\""$1 "\""| getline dte;$1=dte}1' OFS="-500," databars_example_2.csv > databars_example_222.csv

now i just need to change epoch into serial data..... any thoughts?

If you need the date in EXCEL, why not have EXCEL read and interpret the date string?
