[time-nuts] Re: Is there an application for time-stamping with absolute time?

[Magnus Danielson]

Hi Erik,

While one usually is able to achieve it anyway, there is a benefit in 
having TAI or UTC time to measurements, in order to correlate with other 
measurements being done by other instruments. Usually you can deduce 
what would reasonably would be the time by time-stamping the measurement 
as it pops over to some other device. However, sometimes you end up not 
really knowing, so if you can ensure that you got the right time, it 
will indeed help.

However, if getting the right time on the instrument, such that it may 
be wrong or not track UTC properly, then you might have a problem. As 
always, being able to after the fact correct for incorrect time-stamps 
ends up saving data and effort, while not destroying what was originally 
captured. That is however a post-processing concern that would help 
regardless.

So, I would not discourage you, but to take some care to ensure you get 
good time, it becomes another thing to test and verify.

Cheers,
Magnus
