time: make nsec in time.Time an int32 when GC is precise

[alberts]

If possible, include a link to a program on play.golang.org.

I was just browsing through the code for time.Time and found this:

// TODO(rsc): When the garbage collector is completely
// precise, change back to int32.
nsec uintptr

Which version are you using?  (run 'go version' or 'gccgo --version')

tip

Please provide any additional information below.

This change will make time.Times 4 bytes smaller on 64-bit platforms.

No, it won't make it any smaller, due to alignment.
