you have multiple choices:
  1) you can use date/time macros in the destination filename, in which
case syslog-ng automatically opens a new logfile whenever a given
interval passes. in this case you still need a cleanup mechanism, that
removes old logs.

  2) you can write a single file from within syslog-ng and have
logrotate rotate it for you
