Hi Nick,
Thank you for your response. Let me give the 2 scenarios I have tried.
Scenario-1 : Native build
Using this, I have got the FreeRDP 3.5.1 installed and setup and pointed to
this version of the library for Apache Guacamole Server build by building
the staging/1.6 branch. I see the time sync happening in this scenario.
Scenario-2 : Docker build
Using this, docker build on staging 1.6 branch builds by pulling the latest
FreeRDP version 3.15.0 with which I don't see time sync happening.
Clarifying your questions.
* Is it working fine with versions prior to 1.6.0 in both Docker and native
environments?
*The latest release of Apache Guacamole Server 1.5.5 doesn't seem to
support time zone redirection as it is using FreeRDP2 but we see timezone
redirection is supported in FreeRDP >= 3.0.0 according to this.
(https://github.com/FreeRDP/FreeRDP/wiki/Time-Zone-Redirection
<https://github.com/FreeRDP/FreeRDP/wiki/Time-Zone-Redirection>) *
* What does "pche" mean ("pche guacamole client container")?
* Sorry it's Apache. It's a typo.*
* Is it only using a containerized guacd that causes it to fail? Or does
how you're running the client (container vs. native) also have an impact?
*I see that it's not the containerized guacd that causes the timesync
failure. It's the version of FreeRDP that it's using. FreeRDP 3.5.1 can
sync the time zone but don't see that with 3.15.0 / 3.11.0*
* Are your users and connections in the container environment configured
identically - in particular, any timezone settings for the users and/or
connections that are different?
* Settings are the same for containers as well as native runs*
* What messages do you see in guacd container logs, particularly while in
debug mode?
*Standalone run logs (built staging/1.6 with FreeRDP3.5.1 ). Can see
the tzid passed in the debug logs.*

I don't see any event viewer logs / events for timezone on the server side.
It just says connected and disconnected.
Please let me know if any further information is required from myend.
