Please read the Posting Guide. One of the suggestions given there is to provide a reproducible example... a sample of data is a good start.

You say this is related to daylight savings time in the subject line, but I don't see how that relates in your description. Perhaps you should provide a sample of data near the autumn time transition. Please use dput to generate R code that we can load your sample data easily.
