[time-nuts] Timestamps in audio files?

As an adjunct to the thread about timestamped samples of LORAN
transmissions...

Are there any standard consumer-type audio file formats, that support
absolute time time/datestamps? Would not have to be done continuously, but
something like a time and date stamp inserted nearest each sample on a
second boundary.

I have worked with some analog tape audio formats in the past where
IRIG-type timestamps were written on a separate channel or on a subcarrier.

I know of many proprietary digital recording applications that make WAV's
or MP3's or proprietary codec formats, where the filename includes a
timestamp. Much more interested in standard formats where the timestamp is
embedded in the file itself.
