File IO without overwriting file

I don't want to get off topic but,

In the past I have played with reading system time from the Driverstation system clock and sending that over to the cRIO through the dashboard.

In Java there is no way to overwrite the system clock on the cRIO because the JRE doesn't allow access to the clock, you could do it with a JNI system call but I never went that far.

If you don't care about updating the system time on the crio, you could simply get a timestamp from the driverstation on robot startup and keep it in a variable and use that for time stamps, and use System time as a couter to count time since your "time sync".

Hope this helps,
