jmc noted that I didn't include my actual line, so here it is.
First I was using only
.Dd $Mdocdate$
but that warned me
mandoc: ./files/varnishreload.1:2:2: WARNING: missing date, using
today's date
so I did what I was told, according to mdoc(7)
.Dd $Mdocdate: May 19, 2019 $
but it still warned me
mandoc: ./files/varnishreload.1:2:2: WARNING: cannot parse date, using
it verbatim: $Mdocdate: May 19, 2019 $
So I removed the comma and mandoc(1) was happy.
.Dd $Mdocdate: May 19 2019 $
What should be used here? Either I'm warned or I'm using undocumented
syntax, both seems wrong to me.
