time_machine

Easy way to change sytem time on linux and reset back to the correct time using NTP while automatically resolving timezones.

Description

I needed a quick and easy way to change time on linux in order to run integration test for another project. Be sure and disable your local systems NTP service or as in Ubuntu "Automatic Time Zone".

Install

git clone git@github.com:babinc/time_machine.git
cd time_machine
cargo build --release

If you want to run time_machine without root privilages add the CAP_SYS_TIME capabilities to the executable

sudo setcap CAP_SYS_TIME+ep <path to time_machine executable>

Usage

Set time to 8:30 am:

time_machine -t 8:30:am

Reset to correct time using NTP:
