times.TimeInfo isn't getting initialized?

[cy]

    import times
    
    var ifo = getGMTime(getTime())
    echo(ifo)
    
    
    
    Warning: Cannot prove that 'ifo' is initialized. This will become a compile 
time error in the future. [ProveInit]

I've looked over the code in times.nim, but getGMTime just returns 
tmToTimeInfo(), which just returns a TimeInfo(...) constructor. How can it not 
prove that was an initialization? Am I doing something wrong?
