There was a problem hiding this comment.
I'm confused: doesn't fullPath already include name?

Yes it does, but fullPath is dependant on the goroot of the machine you're building this on... So some machines these files will come before the other files, and some after.
So on Andy's machine the file order would be:
/andys_go_root/src/time/format.go
/andys_go_root/src/time/sleep.go
/andys_go_root/src/time/sys_unix.go
/andys_go_root/src/time/tick.go
/andys_go_root/src/time/time.go
/andys_go_root/src/time/zoneinfo.go
/andys_go_root/src/time/zoneinfo_read.go
/src/time/time.go
... but on Zoe's machine it would be:
/src/time/time.go
/zoes_go_root/src/time/format.go
/zoes_go_root/src/time/sleep.go
/zoes_go_root/src/time/sys_unix.go
/zoes_go_root/src/time/tick.go
/zoes_go_root/src/time/time.go
/zoes_go_root/src/time/zoneinfo.go
/zoes_go_root/src/time/zoneinfo_read.go
See the issue for an explanation.
With this change the order will be identical on any machine because they'll be like this:
/src/time/__format.go
/src/time/__sleep.go
/src/time/__sys_unix.go
/src/time/__tick.go
/src/time/__time.go
/src/time/time.go
/src/time/__zoneinfo.go
/src/time/__zoneinfo_read.go
