How do i get the unity of .csv log data from spark?


I log the Spark application with csv-sinks:
*.sink.csv.class=org.apache.spark.metrics.sink.CsvSink
*.sink.csv.period=1
*.sink.csv.unit=minutes
worker.sink.csv.period=1
worker.sink.csv.unit=minutes
master.source.jvm.class=org.apache.spark.metrics.source.JvmSource
worker.source.jvm.class=org.apache.spark.metrics.source.JvmSource
driver.source.jvm.class=org.apache.spark.metrics.source.JvmSource
executor.source.jvm.class=org.apache.spark.metrics.source.JvmSource
Mostly the files have the header "t,value".
t equals a timestamp, but how do i know the unity of the value?
Is it alway the number of bits? Or bytes?
