Only 046 "Special coded dates" uses dates coded to ISO 8601 and edtf, I think. 37X $s and $t have been populated with dates as the elements are described in RDA: normally just the year ("normally" in that I haven't seen any more specific dates in 37X, but I haven't searched for them either, so some may be lurking). I think if I didn't know a definite year, I would record it in 670 but not in 37X.

Subject: [PCCLIST] 37x $s and $t dates

I attended the RDA-NACO training webinars this past week and in that setting forgot to ask the following question, which might be of interest to others.  So I'm passing it on to the list.

Am I correct in assuming that the only date format available for the 37x $s and $t is the standard ISO 8601?  And if so, posting approximate dates in coded form in these fields isn't possible (e.g., "left the medical field to become a bricklayer in the 1950s")?  The $2 refers to the content of other subfields.  Using $8 to link between a 37x and a proxy 046 $s/$t is verboten in the NAF.
