Daylight Saving Issues on Interactions Report and API call data

I have set up and been running an API call to the Report set up on Liberty Converse and have seen an issue with Daylight Saving that when the clock go back any client who is in a call that spans 1am and 2am will bring back a Duration of minus time. And conversely when the clocks go forward it will add an hour onto the call duration. Anyone else seen this issue? I know it may be a rare occurrence.
