Like everyone else stated, it just keeps timestamps accurate, and is also handy if you have a date/clock organizer. (limpidclock and tinymeter in my case) If you want to maintain accurate system time, and you have no/a bad RTC, you could also use a tcp/ip based NTP system to "set" the clock when you log onto the net. (Only useful if you log in every time you would boot your Amiga and use it as a clock) I can't remember any specific proggies offhand, but there's a few on aminet that will do that. If you use Miami, the TCP/IP "side menu" has a Get time [checkbox] from [blank textline], which you can use to do the same, I'm sure MiamiDX and Genesis would have the same option somewhere. (Just need to google an NTP server)
