-tsspell- is from SSC. Please remember the longstanding and explicit
request to explain _where_ user-written programs you refer to come
from.
For this I would reverse time temporarily.
gen negdate = -date
tsset negdate
tsspell, pcond(harvest)
tsset date
However, it seems that you have gaps in your data. In which case
sort date
gen negtime = - _n
tsset negtime
may work better for you.
