YES. you have a MSW inverter. And MSW inverters often do this
There are three types of electric clocks, one uses an internal time base, this is very accurate on the short term, but long term needs re-setting every once in a while.. Your digital watch is an example of this type of clock
The second type is the old analog clock with a synchronous motor. this Syncs up with the power line frequency.. I do not think a MSW inverter would bother it
The Electronic digital is #3, it also uses the power line as it's time base.. Short term it may gain or loose as much as a second or two (if fed proper power) but long term, it might gain or loose as much as a second or two.. In short, very good for keeping time.
However if you use a MSW, where the wave form instead of being anice smooth curve, looks like a STILE (A word that describes at least 3 things. I will list below) the clock may count each step in the waveform as a transistion.. Thus running several times faster than it should.
STILE, is a set of steps which cross a fence, enabling people to step over, but farm animals are not able to climb out of the pen.. (This is the one I"m using above)
STILE: in one group of science fiction novels (Forget which but GOOGLE tothe rescue, Adapt) Citizen Blue, also known as the Blue Adept, his name is Stile
And the third meaning of STILE.. a pile of Dung
You see, Citizen blue, back when he was known as Stile (A Slave name) got that name when he came to the attention of his master because he noticed some parasites in a pile of horse dung, and thus saved a very vaulable horse.
And that's all I'll tell you about that book.
But the wave form of a MSW inverter
Looks like the first Stile.. (Set of steps)
And each step, is being counted by our clock
here as with a True Sine Inverter.. You have a wave form that looks more like the path the dog takes when he jumps over the fence (Actually the wave is a pure sine wave, and the path of the dog is not, but, I think you can see it's a smooth transistion with no steps)
