Raspbian: limit size of log files?

If you mean the foundation's recommended images of raspbian wheezy, then logrotate runs at about 06:25 daily. syslog is rotated daily for a week, and most other logs weekly for four weeks.
If your Pi is never up at that time of day, then "sudo apt-get install anacron". Now logrotate should also run at boot time if it is overdue.
If your Pi is never up for more than an hour at a time and has no network connection, then the time will be essentially static. Otherwise, I do not think the lack of RTC has much impact.
Even with no rotation at all, to fill a 4GB card after a few weeks you must be seeing orders of magnitude more logging than I am. I do not think rebooting a few times a day would make such a big difference. There probably are usages that would cause much higher logging, but I would expect there to be an obvious pattern to the excess logs in that case.

Hi, if you want to know if logrotate is installed use
dpkg --list logrotate
If it's not installed you'll get a message something like "dpkg-query: no packages found matching logrotate"
