Automating The Semi-Automatic 'rdate'
Originally written by
- The most crude form of time synchronization will mean putting
an 'rdate -s' command in a cron job.
- How often to run this job? sometimes once a day will suffice.
- If you need a more accurate clock (e.g. your machine's clock runs off
quickly), you may want to run 'rdate' more often.
- For some kind of operations this will not suffice (e.g. compiling
source code that resides on an NFS server, which is edited via another
machine - 'make' will not like even tiny time mismatches).
