Downloading CSV with times in UTC

[sp acbell]

Hello, I tried downloading my data, and I noticed that some of the times are wrong during Daylight Savings.  The date/times appear to be local time, however, on Daylight Savings days, my data refers to times that don't exist (for example 2am on 2017/3/12, which doesn't exist in Daylight Savings time) or ambiguous, like 1am on 2014-11-02.  Is there a way to get the timestamps in UTC format or an epoch timestamp so that I can do the conversions myself?  Thank you
