The recipe originates from meta-y2038 where the name was not confusing, but in oe-core it is. (From OE-Core rev: 90bc7a66b08580207839fc6aafe1ac86c12981c5) Signed-off-by: Alexander Kanavin <alex@linutronix.de> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

# To simulate Y2038 occurring in qemu, add to your build configuration:

|
# QB_OPT_APPEND:append = " -rtc base=2040-02-02"
|
|
#
|
|
# Note that this does result in ptest failures on qemux86:
|
|
# perl python3 dbus openssl glibc-tests openssh curl glib-2.0 tcl libmodule-build-perl
|
|
# and a subset of those occurs in qemux86-64 as well:
|
|
# curl python3 openssl openssl tcl python3-cryptography
|
|

|

# Working to address those (before Y2038 rolls in) will be appreciated.
