val format : (module Format) Base.ref

Determines the format of durations when reading am_recording_environment_variable and when printing results. Defaults to integer nanoseconds with a "ns" suffix.

Core_kernel.Time_ns overrides this to use Time_ns.Span.to_string on input and Time_ns.Span.to_string_hum on output.
