Have you checked your timezone settings?
I noticed in your thread that you are observing traffic totals that seem to reset between 8 am and 2 pm. From the looks of it, you must have timezone settings for your account set to the wrong timezone.
This article describes how to change timezone settings for your account:
Another thing to keep in mind is that anytime you are looking at a report, that includes data from the past 24 hours, Google Analytics uses data sampling to estimate the traffic based on a sampling of the data, so it isn’t showing actual data, but an extrapolation based on sampling. Also, any reports that contain a lot of data will always be based on sampling, unless you upgrade to the Premium Google Analytics.

Google Analytics does indeed have realtime reporting, however, it is separate data from normal reporting, and it only stores 30 minutes of data.
Data for regular reporting is processed only once a day by Google analytics so there will typically be some discrepancies if you are looking at reports that include data from the same day.
