Discrepancy with Reporting due to time zones

I opt into the daily, weekly and monthly chat analtyics automated emails that are set up in the settings > personal > email reports section. The time zone for those email reports default to UTC 0 and do not adjust according to the account settings (I am EST). So the usefulness of these reports gets diluted for anything within 5 hours 12am UTC. For example a chat taken at 8pm EST on Jan 5th will count towards Jan 6th. I really like the info translated on these email reports but this makes the data confusing and not always accurate for my use.
