I would take it as a glibc bug / lack of optimisation. At least definitely one |
| 8 |
where the fault lies in glibc given that your showed other libc as more |
| 9 |
optimized. |

|
| 11 |
And given that POSIX puts ":/etc/localtime" as implementation defined[1], |
| 12 |
I think we should avoid it, glibc isn't alone in dealing with timezones. |
