Dear All. Has anyone been using the time bit of the w3cdtf in mods:dateIssued or any of the other date fields in originInfo? I just note that the format allows the expression of time (Thh:mm), but the MODS guidelines don't mention the use of it. We are describing off-air recordings of radio broadcasts, so capturing the start time of the broadcast is important to us. Many thanks, Matthew Herring University of York Library and Archives (UK)
