What's going on here? It seems that when $REPORTTIME >= 1, no time
output is ever produced.
The exact values here are unique to sleep, but similar behavior can be
observed for other commands, too, albeit at different thresholds.

REPORTTIME
If nonnegative, commands whose combined user and system execution
times (measured in seconds) are greater than this value have timing
statistics printed for them.
Note the difference between elapsed time (total) and cpu time (user +
system) in your output.

Ah, thanks. And I guess REPORTTIME is rounded down to an integer
value. That would explain it.
