About Set/Get PLC time function

[whitetiger21022014]

Hi Robinson,
PGClockWrite (implement GetPLCDateTime) , is it a mistake between 2 functions?

//implement GetPLCDateTime
func (mb *client) PGClockWrite() (datetime time.Time, err error)

//implement SetPLCDateTime
func (mb *client) PGClockRead(datetime time.Time) (err error) {

hi when you use PGClockRead to set time of plc，do you produce a panic?

I believe there are multiple issues in datetime.go
PGClockRead / PGClockWrite function names are reversed - just confusing
mb.send does not catch error and so will panic if PLC is disconnected
s7.SetDateTimeAt(requestData, 32, datetime). I had to change this to s7.SetDateTimeAt(requestData, 31, datetime) to format date correctly.

PS. I am new to github. Happy to post my fixed datetime.go if required
PPS. Great job with gos7.
