How accurate is ADXL345 internal oscillator?

How accurate is ADXL345 internal oscillator?  Since the internal clock isn't output from device, this probably doesn't matter as I probably have to either enable the DATA_READY / WATERMARK interrupt or constantly poll register 0x30 to see if new data is available.

 

I'm trying to do an FFT on the data from the ADXL345.
