Note: By "Disable" daylight savings time, I mean for the system clock to ignore any time changes for daylight savings time (ie, if DST is disabled, then the clock will not "spring forward" an hour in March and will not "fall back" an hour in November.
I am designing an Qt application to run on Ubuntu 18.04 and I need to be able to set system timezone, time and date.
For settings time and date, I can easily use timedatectl to modify the system settings. However, this command does seem to be able to disable Daylight Savings Time. It does report whether DST is "Active" or not depending on the timezone and date, but you cannot disable/enable this settings.
On Windows, I had used tzutil.exe to setting DST enabled or not using the dst_off flag. Is there are any equivalent to Ubuntu?
