It looks like this function was converting the time (`windows.NsecToTimespec()`),
only to convert it back (`windows.TimespecToNsec()`). This became clear when
moving the lines together:
```go
ctimespec := windows.NsecToTimespec(ctime.UnixNano())
c := windows.NsecToFiletime(windows.TimespecToNsec(ctimespec))
```
And looking at the Golang code, it looks like they're indeed the exact reverse:
```go
func TimespecToNsec(ts Timespec) int64 { return int64(ts.Sec)*1e9 + int64(ts.Nsec) }
func NsecToTimespec(nsec int64) (ts Timespec) {
ts.Sec = nsec / 1e9
ts.Nsec = nsec % 1e9
return
}
```
While modifying this code, also renaming the `e` variable to a more common `err`.
