"calculate time" is a correct and usable phrase in written English.
You can use it when you need to figure out how long it will take to complete a task or when you want to determine the time difference between two events. For example, you can say, "Let's calculate time and make sure we leave early enough to arrive at the meeting on time."
Since common experience shows how imprecise these estimates are, people generally calculate time from such indicators as the position of the sun or with clocks and watches.
On the other hand, if your response was something along the lines of, "I am an adult human being, and your assumption that I calculate time in a measurement as infantile as sleeps is both the strongest possible insult to me and a tremendous embarrassment to this publication," then we're going to be fine.
Stopwatches were used to calculate time to consumption and dry matter intake rates (DMIR).
Birth and finish dates were used to calculate time to finish and finish weights were also compared.
The dynamic mass balance is solved numerically to calculate time profiles of substrate and product in the fermentation process.
This approach uses simplified analytical models to calculate time series of short-term utilization ratios, defined according to the DnV-OS-F201 (2010) standard.
Using a panel of 34 OECD countries over the period 1985–2013, we calculate time-varying Okun's coefficients for each country.
The developed model is integrated into a computational scheme to calculate time-response of the drillstring system in the presence of stick slip excitations.
We proposed the use of simple equations to calculate time-dependent sensitivity and specificity based on published survival curves and other time-dependent indicators as predictive values, likelihood ratios, and posttest probability ratios to reappraise prognostic marker accuracy.
In particular, TRNSYS calculates transient heat conduction through multi-layer envelope components using the transfer function method (TFM), recommended by ASHRAE as one of the most accurate methods to calculate time-variable heat loads [20].
The model formulation is based on the two dimensional orthogonal collocation on finite difference (2-OCFD) and method of generating functions (GF) which was properly adopted to calculate time-conversion behavior of styrene-methyl methacrylate copolymerization.
