The last line (END_DATE := START_DATE - interval '3 year';)

Hint: Could not choose a best candidate operator. You may need to
add explicit type casts.
Context: PL/pgSQL function "lost_hours_temp" line 10 at assignment
Note that the error is at line 10. You've only shown lines 1 through
7 of the function body, so you haven't actually shown us where the
error is.
