Firepower NTP Temporal Anomaly

Infuscomus — Tue, 12 Mar 2019 09:41:20 GMT

I'm making a CISCO router get the time from country specific ntp.org's servers (GMT+2).

It functions correctly but does not adjust to daily savings (GMT+3). Not a big problem here. I don't want that anyway.

Then, I synced the ASA firewall and Cat switch after the router. All good here, time gets transmitted again with no DS.

Now I'm trying to also sync the time of the Firepower module.

Here I have a problem: the Firepower seems to be able to read the time from the Router, since it answers correctly when I use something like ntpdate -u RouterIP, but the time shown is UTC/GMT instead of UTC/GMT+2.

To recap:

Router shows correct GMT+2 time.

Firewall shows correct GMT+2 time.

Catalyst shows correct GMT+2 time.

Firepower shows incorrect GMT+0 time.

Note: using the localtime parameter instead of UTC had no effect.

How can I make Firepower sync to GMT+2, like the rest of the devices ?

NTP always communicates the time as UTC without any DST-information. The summertime has to be configured on each device individually.

I'm not interested in summer time (which I find to be an absurdity anyway); I just want to make the device display UTC+2 which is local time, not UTC.
