Is it possible to use your Virtual Time Clock to track how much time you spent on a work-related travel. For this, there are the options Start Travel and End Travel.
It's important to understand that those options should be used together with Start Work and End Work.
You have to travel to the customer site by train, therefore you select the option Start Travel when you get on the train.
When you arrive at the site, you select the option End Travel and then select Start Work.
After the work at the customer site is complete, you use the option End Work.
Use Start Travel when you start to make your way back, and when you arrive at your destination, select the option End Travel.
