Working Time Nodelist Flag (FSC-0062)

CM (Continuous/Crash Mail) flag indicates that the node is available at any time of day and night. This means that working time of the node is 00:00-24:00.

Availability flag for non-CM nodes indicating the hours during which the node is available in addition to ZMH (see chapter Calling a Node only within its Working Time for ZMH definitions). This must be in accordance with the recommendations in FSC-0062 and the reference table reproduced below. This flag appears in the Nodelist entry as Txy, where x is a symbol for the opening time and y is a symbol for the closing time. All Txy flags must be specified after U, which is an attribute of extended Nodelist flag.

ATTENTION : All times must be UTC (Universal Time Coordinated)!

Argus is using this flag for polling a node in its working time.

Argus allows the combing of working time intervals by using several Txy flags. For example, TCh, TSW means that node is available 2:00-6:30 and 18:00-22:00 UTC.

Argus also supports TxyL extension - it is the same as Txy, but indicating that the time is local, not UTC. For example, TCSL means 2:00-18:00 local time.

CM flag is equivalent to U,TAA.
