How I can to put all in same Timezone because I have some errors when gantt change automatically some tasks.


Hello Pedro,
Gantt stores the start_date an end_date in the Date format. So, it is handled by the browser. If you see different time zones, it means that some dates are in the summertime and others are in the wintertime. There is no way to change that:

Please, clarify what kind of issues you have.

The problem is with the auto Schedule when I delete or and a link or move the task fowards/backwards the autoSchedule change the dependencies task and leave the hour in the past day at 23h, ans all the dependencies stays like TR04 to the last dependence, on the left side is the error and on the right side it´s ok.

Hello, thanks for the help.
I update the version of gantt to the latest version and it´s start to work correctly.
Looks like the version 7.1.4 has the config parameter “gantt.config.server_utc” always true, even if I put the value false.
