bysort prefix with date format in asdoc messes up the date order

Hope you are doing well with your endeavors. I have greatly benefited from your asdoc program in Stata and have used this in my first research paper. While using it again I came across a little query and was not able to resolve. I am running the follow command in Stata but the dates are not shown in their quarterly formats rather they get the random numbers: bys Time_period:asdoc sum var1 when I use the same code without asdoc command, the dates are shown in their proper format like 2019q1, 2019q2 etc. bys Time_period: sum var1 I believe this is something that asdoc fails to pick up and present in its proper format. It would be kind enough if you can clarify this bit. Thanking in anticipation
