# How do I ensure the camera's clock is accurate?

1. Decide on a time zone you will use over the course of the project. Typically this is either your home time zone or a time zone you travel to.
2. Set your GPS device to display time in the chosen time zone.
3. Start setting the time on your digital camera.
4a. If your camera allows for setting seconds to zero, do so when the clock on the GPS device jumps to the next minute.
4b. Otherwise set the time on the camera to the next full minute. Save the newly set time at the very moment actual time on the GPS device catches up.
In order to be able to geocode images from a GPS track log, it is important that the camera clock is accurate. It is even more important that the camera clock is not modified over the course of a project.
Once you start working within HoudahGeo, you should check the camera's clock against the GPS clock. You can now specify the exact clock error.
