Unlike my previous blog discussing time, this one has nothing to do with time travel. Rather it is a small criticism of a recurring theme with the Dejah Thoris series from Dynamite. It is common throughout the series that time is referred to by the Martian terminology, not by the Earth terms. For instance:

Equally in the same issue there is the following panel:

This panel shows that they use years even if they do not use the usual breakdown of hours and minutes. This is fine though. Hours, minutes and seconds are primarily human inventions, taken by dividing the length of a day by a certain amount (though there are other modes of measurement for this, for instance that a quartz crystal pulses roughly every second). Years and days still exist, as a day is the amount of time it takes for a planet to rotate completely (not completely true) and a year is the time it takes for a planet to revolve around a sun (interesting fact - the year on Neptune is nearly 165 times the length of our own, so since it discovery in 1846, it is only just started its second year since we discovered it.)

My issues here though is not so much with the time units themselves, but rather why they are not translated. Every other word in the series is translated from Martian to English, but these words are not. Of course the exact definition is not going to be accurate, but instead of saying "several xats" the character could say "ten minutes".
