Description: This attribute specifies the scheduled times at which data should be collected. Only accounting applications need the capability to generate data in this way. Setting this attribute for other streams has no effect.

The user can enter the times in any order and duplicates are prevented at data entry. There is a limit of 24 entries, which is imposed at semantic check time. The collection times are triggered in chronological order. A semantic check error is issued if any 2 entries are less than 1 hour apart or if any 2 entries are more than 12 hours apart (which implies that if any entries are provided, there must be at least 2 entries).

Note that by default (that is, in the absence of a provisioned schedule), a Virtual Circuit (VC) starts its own 12-hour accounting timer. If any collection times are provisioned here, then the Time- Of-Day-Accounting (TODA) method is used in place of 12-hour accounting. This is applicable to both Switched VCs and Permanent VCs.
