It is the frequency (in Hz) of the clock that increments the Time Base Register (TBR). After reading TBR (or calculating a difference between two TBR values) you can use "timebase" to convert to real time units, such as microseconds/nanoseconds/picoseconds. For debugging I log events together with a TBR reading, which I can later convert to a time from reset (or a time from the moment when the kernel initialised TBR to zero, which happens in some kernels).
