How to change time from command line without messing up with SSL handshake












0















I am using Linux in an embedded machine and would like to implement time/date change functionality. I discovered and tried to use timedatectl, but it caused a couple of problems in my Qt application.



What I do when I want to change time is,



timedatectl set-local-rtc true
timedatectl set-ntp false
timedatectl set-time .....
hwclock --systohc


I can always get back to using Network time with:



timedatectl set-local-rtc false
timedatectl set-ntp true


However, as soon as I set NTP to false, I get SSL handshake errors (i.e. QML Image: SSL handshake failed) when I try to make a request from an API in my Qt application. This problem occurs at several places. I simply want to be able to turn on/off network time and adjust time on a Linux system. Any ideas how to tackle this issue would be greately appreciated.
