Daily Usage messed up on Time Change

My kWhd feed got messed up on the time change. My normal daily usage is about 7-9 per day but for some reason it shows over 120 on the day of the time change. The realtime feeds are correct but the daily one is wrong.

Any suggestions of preventing this? Fixing the entry? I’m using my own install of Emoncms.
