I am going to forward the problem to the vm mailing list. bye Nicola <div class="moz-cite-prefix">On 11/3/21 12:05, Gerald Klix wrote: </div> <blockquote type="cite" cite="mid:5e6701a6-7039-4729-d033-d3d77a95ef61@klix.ch">Nicola, If you look at <a class="moz-txt-link-freetext" href="https://github.com/OpenSmalltalk/opensmalltalk-vm/blob/634e4e3c8556a72d54f43beefc3069c60e594a21/platforms/unix/vm/sqUnixHeartbeat.c#L139" moz-do-not-send="true">https://github.com/OpenSmalltalk/opensmalltalk-vm/blob/634e4e3c8556a72d54f43beefc3069c60e594a21/platforms/unix/vm/sqUnixHeartbeat.c#L139</a> you see that "vmGMTOffset" is added to the new time.

I have 2 services running in Cuis in 2 independent Linux/Debian servers. . In weekend in Italy we changed time from CEST to CET . The OSes changed time correctly . But Cuis services are 1 hour forward !?!? . If i run a fresh new Cuis now in my laptop (Linux/debian vm), I see it has the correct time, corresponding to the OS time . I did not change my localTimeZone in Cuis, in any machine. It is acceptable for me it says UTC even if it is actually localtime. . Seeing 'DateAndTime now' I discovered that Cuis by default uses primLocalMicrosecondClock, so it should always use the OS local clock and think it is in the UTC timezone. But, it is not doing so on images that were started some days ago (max 20). It does so on new run images. I don't know well how to fix this. Maybe some time config is made when Cuis starts up? It seems it is remembering the time when it was stared. EXTRA. NOT IMPORTANT AS THE PREVIOUS. If there are some changes to make I have a suggestion for improvement. Could we set localTimeZone to "system", or "local" ? At present we are reading localTime from the OS and setting to UTC. Which is a bit confusing. bye Nicola </blockquote> </blockquote> </blockquote> </body> </html>
