date of interview in IPUMS-USA ACS data

Because the reference period for the ACS survey depends on the date of the interview, is there any way to know when the questionnaire was answered? Something like a date of intrerview variable? Or even just quarter or month? (I am looking at the IPUM-USA and cannot seem to find this information). Thanks a lot for any suggestions!

Unfortunately, the Census Bureau does not release any information about when respondents were interviewed
