Specifies the period in milliseconds at which the device management service is queried for device policy information.
Setting this policy overrides the default value of 3 hours. Valid values for this policy are in the range from 1800000 (30 minutes) to 86400000 (1 day). Any values not in this range will be clamped to the respective boundary.
Leaving this policy not set will make Google Chrome OS use the default value of 3 hours.
Note that if the platform supports policy notifications, the refresh delay will be set to 24 hours (ignoring all defaults and the value of this policy) because it is expected that policy notifications will force a refresh automatically whenever policy changes, making more frequent refreshes unnecessary.
