Contracts follow the general rule that applies to calls and the installed base when MTZ is active. All contract dates and times are relative to the time zone of the end user on the contract.

The system searches for call coverage using the call open time relative to the end user’s time zone. It also determines if the day is a holiday, relative to the end user’s time zone.

For contract coverage to be considered valid, the call open date must be within the contract line’s start and end dates. The contract’s currency must also match the call’s. If more than one service type applies to call item, the system checks to see if the call’s open time falls in the available hours for the contract line’s service type.

The system uses the same algorithm to determine limit consumption when you post a call invoice. It uses the call open date relative to the end user’s time zone to determine the effective limits. You cannot modify the start and end dates of the contract header or lines to exclude an attached call’s open date. This is also true of limit records. You cannot modify the effective dates to exclude the open date of a call that references them.
