I am running openwrt_cc, and having trouble with time+date based firewall rules. Time based rules (without date) work fine, but as soon as I add the date, the time no longer works. I expect such rules to take effect at the specified times within the specified dates. The resulting iptables do not look right. See below.

PKG_NAME:=firewall
PKG_VERSION:=2015-07-27
PKG_SOURCE_URL:=git://nbd.name/firewall3.git
PKG_SOURCE_VERSION:=980b7859bbd1db1e5e46422fccccbce38f9809ab

firewall uci:

config rule
option name 'lan-00:16:3e:d2:96:cf'
option src 'lan'
option dest 'wan'
option proto 'any'
option target 'REJECT'
option src_mac '00:16:3e:d2:96:cf'
option start_date '2018-04-10'
option stop_date '2018-04-11'
option start_time '20:30:00'
option stop_time '20:40:00'

iptables entry:

0     0 zone_wan_dest_REJECT  all  --  any    any     anywhere             anywhere             MAC 00:16:3E:D2:96:CF TIME from 20:30:00 to 20:40:00 starting from 2018-04-10 01:00:00 until date 2018-04-11 01:00:00 UTC /* lan-00:16:3e:d2:96:cf */

Notice the date values are followed by "01:00:00" which doesn't seem right. I can't seem to control these values in any way from the uci.

jow-:

The values stem from the kernel timezone offset, try setting option utc_time 1 in your rule. Furthermore your used firewall version is quite old, please try to reproduce the problem on a current version.

Correction, I tracked it down to the use of mktime() instead of gmtime() - this causes the firewall to generate timestamps with the local timezone offset.

Bug appears again in (device is a netgear R6220) running
Powered by LuCI openwrt-19.07 branch (git-19.309.76540-c0e73d3) / OpenWrt 19.07.0-rc1 r10649-c4fdb377a2

All day of the week based rules are ignored. Only time based rules are taken into account.

Sample non working rule :

config rule
option proto 'tcp udp'
list weekdays 'Wed'
option src 'lan'
option name 'T Mer'
option src_ip '192.168.99.192/27'
option target 'ACCEPT'
option start_time '14:00:00'
option stop_time '16:30:00'
option dest 'lan'

Sample working rule :
config rule
option proto 'tcp udp'
option src 'lan'
option name 'T LunMar'
option src_ip '192.168.99.192/27'
option target 'ACCEPT'
option dest 'wan'
option start_time '18:15:00'
option stop_time '19:15:00'

Working rules stops working when explicitely selecting all seven days of the week.

Working/not working means the rule does not appear in the firewall rules list once changes have been saved. And thus are not applied to trafic.
