Bash Version: 4.2
Patch Level: 37
Release Status: release

Description:
	The time builtin does not work with set -e when a command fails.
	The "time" builtin should give timing for a command regardless of exit status.

	Examples:

	# 1. with set -e, the time builtin is silent for failed commands (this is the bug)
	$ bash -ce 'time false'

	# 2. normally the time builtin gives times for failed commands
	$ bash -c 'time false'

	real    0m0.000s
	user    0m0.000s
	sys     0m0.000s

	# 3. the time(1) utility gives times for failed commands with set -e, of course
	$ bash -ce 'command time false'
	Command exited with non-zero status 1
	0.00user 0.00system 0:00.00elapsed 0%CPU (0avgtext+0avgdata 1664maxresident)k
	0inputs+0outputs (0major+150minor)pagefaults 0swaps

Repeat-By:
	$ bash -ce 'time false'
