SDI Clock Time

In general, the local SDI clock time only needs to be approximately correct (within a few minutes) since navigation and image start times use the image time transmitted in the signal. One exception to this is DMSP which uses the local clock on the SDI to help in the navigation of images.

SSEC installs xntp on SDI configurations that are local time sensitive (like DMSP). For all other configurations, it is the SDI user's responsibility to maintain the time.
