D Time type
D Local standard time or UTC: Defines the time zone the data refers to.
Caution: In the last hour of daylight-saving time or the first hour that fol-
lows in standard time, it is possible for time entries to be ambiguous. If the
time is acquired via ISDN or set manually during this time, then it is always
assumed that the time entry is in daylight-saving time.

12.7.1 Regular Execution of Commands
This feature is intended to allow the device to execute predefined commands
in a telnet-like environment, at times defined by the user. The functionality is
equivalent to the UNIX cron service. Subject of execution can be any BAT
command line command. Therefore, the full feature set of all BAT devices
can be controlled by this facility.
Application examples:
D scheduled connection
Many leased lines disconnect automatically after 24 hours of continuous
operation. This enforced disconnection can have some unwanted side-
effects for example if it happens to an unsuitable time during the day,
because e.g. the VPN tunnel is disconnected and the IP address of the
BAT is changed. To control the disconnecting time a manual disconnec-
tion can be set e.g. at midnight, so it can not happen at an unsuitable
time.
As a second example devices with a distributed network with only
dynamic IP addresses can build up a connection at a certain time to a
VPN gateway, so that data can be transferred safely. This way a pro-
tected access is even possible without an ISDN connection.
D time-dependant firewall or QoS rules
The firewall and QoS rules are at first temporally constant. But it can be
useful to make variable settings for different daytimes or weekdays. At e.
g. off-hours or weekends different priorities for guaranteed bandwidths
can be set than at business hours.
D regular firmware or configuration updates
