Even in 2016, conversations about the "biological clock" tend to assume that fertility is an exclusively female concern.
This is especially important on virtual machines, where clocks tend to drift more rapidly than normal machine clocks.
All of the different computers have different clocks, and their clocks tend to stray and they don't know whether they're doing something at the same time or not, and these are the issues that distributed systems have had to deal with for years.
Indeed, because the internal clocks of mice [including 3xTgAD (Sterniczuk et al., 2010)] run faster than 24 hours, whereas human clocks tend to run slower (Duffy and Wright, 2005), a change in sensitivity of the clock to light would naturally push the phasing of rhythms in these two species in opposite directions.
In general the molecular clock rate tends to be greater during evolutionary bursts or radiations (if these involve frequent population subdivision [ 165]) and along more recent lineages, than those in the deeper past, because in more recent lineages mutations may be present which, given sufficient time, will be removed by drift [ 166, 167].
New York has a city clock master, who tends to large public clocks, but Mr. Berger, an impish man who dresses like a member of the 1930's English gentry, is the only private clock winder in the city.
When I know that I'm literally up against the clock, I tend to be far more productive.
The local medical community has responded aggressively to this situation, and the health professionals have been working around the clock to tend to patients.
The unbelievable nightmare continues at area hospitals today, as staff works around the clock to tend to the victims of the Boston Marathon twin bombings.
