Hi, as evidenced here [1] the slightly ambiguous wording in the RFC 3339 [2] seems to be the reason that the date utility using the --rfc3339=TIMESPEC switch formats the date with a space instead of a 'T'. I was confused as well, so I took the liberty to mail the authors of the RFC in question. I attached the reply from Mr. Klyne. There is also a patch attached. Regards, F.
