Dates in tables with stata 17

[Martin Weale]

I have a quarterly date variable, x. I can set it up as quarterly using z=qofd(x) and then format %tq z. This converts it into annual/quarterly form when I look at the data using the variables manager. But when I try to tabulate the date using table z to find the number of observations in each date, it comes out as an integer-- the number of quarters since 1960q1. Does anyone know how I can set it into annual/quarterly form in the table, please?

Is your Stata 17 fully up-to-date?

Here is a short example where I'm getting the expected row headers from table.

sysuse auto
set seed 17
gen z = runiformint(100,110)
format %tq z
table z

Here is the reported table.

. table z
