How do I fix the timestamp in the startup log? (Linux x86_64 native)

New here and getting used to cFE.

What I noticed is the timestamps shown here seem to be very off. How do I fix it? Any pointers welcome.

Hello and welcome! cFE has it's own internal timekeeping via the TIME service, aka "spacecraft" time. It's worth noting that time services is fairly complex and was designed to handle a variety of use cases, I won't cover everything here but hopefully this will get you started.
The basics are there's the epoch that's set via configuration, a mission elapsed time (MET) counter, and a spacecraft time correlation factor (STCF).

The easiest way to update time is via the cFE set time command CFE_TIME_SET_TIME_CC or cFE set STCF command SC_TIME_SET_STCF_CC, both of which will adjust the spacecraft time correlation factor (STCF). You could change the epoch, but that's a compile time configuration value. You could also add a simple app that just grabs the time from the OS (or whatever real time clock is available) and sets the STCF for you. More complex systems and/or those with tighter timing requirements typically involve a "tone" and "time at tone", and cFE can act as a timer server or client.

Note there are a few issues open to improve things, specifically nasa/cFE#908 to initialize the STCF from within the PSP, and more general nasa/cFE#302 to really simplify things. Adding in a simple mechanism to update spacecraft time using OS time would be a good improvement.

Thanks for the great answer and great pointers. I am still wrapping my head around cFE. It will be challenging and rewarding. I hope to contribute as soon as possible. I am also developing a low cost Single Board Computer. I hope to get cFE to work on it, so that makers and students can use that to learn how to code for spacecraft.
