This makes it possible, on a system with /usr/{lib,share}/zoneinfo/,
to systematically run a command with TZ set to each system-supported
zone. For example, it can be used to verify that a corelib/time/ test
passes regardless of the valid setting of TZ.

# Usage: foreachzone command [args...]
|
|
#
|
|
# The command is run with eval, so can include embedded shell
|
|
# metacharacters such as | and ||. It is run in a sub-shell, so can
|
|
# change environment or cd to a different directory without
|
|
# complicating later runs of the same command.
|
|
#
|
|
# It is run repeatedly, with the TZ environment variable set to each
|
|
# timezone name in turn, excluding the copies of zoneinfo/ under its
|
|
# posix/ and right/ sub-dirs. Symbolic links are included (as long as
|
|
# they point to valid zone data).
|
|
#
|
|
# For example, in the top level of a build tree,
|
|
# foreachzone ninja tst_qdate_check
|
|
# will run all the QDate tests in every time zone (this may take some
|
|
# time).
