I'm not sure, but that may be what 969264409111 was referring to. In fact any entity that can perceive the passage of time will use units that make sense to it. For us the 'natural' units of time are the day and the year, which are artificially subdivided into hours minutes and seconds. For other species the time division may be much different.

We might not be able to alter their perception of time, but it will be possible to convert between our time measurements and their time measurements (ignoring the effects of relativity).
