| # 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: |
| # |
| # (none known at this point) |
| # |
| # and some ptest failures appear in qemux86-64 as well: |
| # |
| # openssl https://github.com/openssl/openssl/issues/21671 |
| # |
| # Working to address those (before Y2038 rolls in) will be appreciated. |
| # |
| # Note: some issues occur on 32 bit regardless of the date set: |
