Pulsars are highly magnetized rotating neutron stars which emit a beam of light, but detectable by the telescopes mounted in Space. They emit electromagnetic radiation in the form of radio waves. Their observed periods range from 1.4 ms to 8.5 s. The radiation can only be observed when the beam of emission is pointing towards the Earth. This is called the lighthouse effect and gives rise to the pulsed nature that gives pulsars their name. Because neutron stars are very dense objects, the rotation period and thus the interval between observed pulses are very regular. For some pulsars, the regularity of pulsation is as precise as an atomic clock.
If you had ...sorry, you cannot view external links. To see them, please
REGISTER or LOGIN is 642Hz which is the second E above middle C.If the pulses are several seconds apart you could count seconds in elephants: it takes about one second to say "one elephant", "one Mississippi" is also about a second.
What's wrong with keeping an ordinary clock on your ship? It wouldn't stop working differently just because you're in Space. Except if it were a pendulum clock, of course. It would record the passage of local time perfectly well - no worse nor better than when on Earth.
If you lost all power on your ship, you'd have more to worry about than telling the bloody time!
OK....perhaps I should have not placed myself in space but in a locale where I can breathe, eat, drink and be well.........In a room with no windows !!
A not very accurate way could be by measuring hair or nail growth.Hair grows about 1/2" per month, not sure about nails.
