    1919The miniSEED format includes only a start time for each record. The sample rate is encoded in the data fixed record as two two-byte integers. These two integers are treated as multipliers if positive, divisors if negative; this a wide range of sample rate values can be expressed. In converting from Earthworm TRACE_BUF messages to miniSEED, errors would be introduced if the nominal sample rate was used to set the miniSEED sample rate factors. Instead, a '''best''' rate is determined from the starttime, endtime, and sample count values. Then this new sample rate is rounded to the nearest 0.0001 samples per second. This rounded is intended to reduce the discretization introduced by the conversion to the short integer rate factors. Finally, this new sample rate is used to set the miniSEED sample rate factors.
