The assumed time of the pulled ticket is based on when it is received by Command View TL. This
avoids inconsistency with time zones and incorrectly set clocks. In normal operation this works well
because tickets are received within an hour of being pulled (based on the transport interval
configuration) but if the connection to Command View TL is lost for a period of time and then recovered,
the tickets waiting to be sent will all be received at the same time. These tickets will then have very
similar time stamps, causing an unexpected increased in calculated utilization for that time period.
