I have so far added this syntax:
Lowest Temperature at [th0temp-dmintime=apm.ij]:[th0temp-dmintime=apm.kl][th0temp-dmintime=apm.op]
Highest Temperature at [th0temp-dmaxtime=apm.ij]:[th0temp-dmaxtime=apm.kl][th0temp-dmaxtime=apm.op]
I could already have this wrong

Any suggestions would be much appreciated.
