With Windows 10 1809 or 1909 I identify a bug with the Windows time zone in the Citrix HDX Session wiht HTML5 Receiver/Worksapce App only.
On my local client the Windows time zone is well configured and Citrix uses the local time zone of the client.
Workspace App for HTML5
Inside the Citrix Session the time zone is wrong and the DST settings are set to off.
Workspace App 1912 / 2002
If I’m reconnect the session only with the Worksapce App, the time zone is configured right and the DST settings are set to On.
Solution / Workaround
Further investigation’s take place and I’m testing Citrix VDA 7.15 LTSR instead of VDA 1912 LTSR and the time zone is setting in the right way. This issue happens on Desktop OS only with VDA 1912 and not on Server 2016 with VDA 7.15/1912 LTSR.
In addition this happens with the DST end of March first.
The following GPO Settings are enabled by default, but set back to disabled doesn’t help to fix the issue.
I have addressed this to Citrix inside the CTP Forum and hopefully this will fixed in further cummulative updates for the VDA 1912 LTSR.
