The Schedule gate blocks until the current date/time evaluates to the given cron expression, or the configured FlexDeploy group overrides to continue.

Field	Description
Gate Name	The name of the gate.
Description	An optional description for the gate.
Schedule Cron Expression	The FlexDeploy group which is responsible for approving or rejecting the task associated with this gate. Sample cron expressions are provided in the drop-down. Starting in the 4.6 release, multiple Cron Expressions can be specified using semicolon as a delimeter. For example, 0 0 11 ? * ;0 0 12 ? * is equivalent to 0 0 11-12 ? * * This allows for Cron Expressions that are scheduled to run on the 2nd and 4th Friday which is not normally possible with Quartz Cron. A new Admin Screen was added to test expressions in the Administration Menu on the Admin Operations Screen. A new Admin Screen was added to test expressions in the Administration Menu on the Admin Operations Screen.
Schedule Override Group	The pipeline role which is allowed to continue execution prior to the gate completing on the configured schedule. Default role members are defined on the pipeline, and optional overridden for each release.
Precondition	An optional Groovy script which determines whether the gate or step is applicable during execution. The script has access to variables and methods listed in Pipeline Groovy Variables and Methods. You can find these variables methods using Variable Lookup help. The script must return true if the gate is applicable, or false otherwise. If no script is provided, the default is to return true (applicable).
