This data collection represents an attempt to apply recent methodological developments in the measurement of time use to a national probability sample of United States households in order to facilitate development of a fully articulated system of economic and social accounts.
I’m afraid I can’t help with the ICT component, but you might get some out-of-the-box inspiration in the distinction between chronos and kairos of the ancient Greeks (chronos corresponding to the sequential, quantitative, time, measured in months, days or hours, and kairos corresponding to the qualitative time, the window of opportunity). The notion of rhythm, which is often disregarded, is also very inspiring when studying time. I remember an interesting book on the topic, by Eviatar Zerubavel, entitled Hidden Rhythms.
Robinson, John P., and Geoffrey Godbey. Time for Life : The Surprising Ways Americans Use Their Time. University Park, PA: Pennsylvania State University Press, 1999 is a classic, but Robinson has updated this in a number of studies. It's good starting place for U.S. Also, for U.S. look at recent studies by Kaiser Foundation on youth time and screen use and Pew Project on Internet and Public Life.
One of the best recent studies overall is Judy Wacjman,of LSE: Pressed for Time: The Acceleration of Life in Digital Capitalism, Chicago, 2015. Another more social theoretical piece (so is Wacjman, but more synthetic) is Helga Nowotny, Time: The Modern and Postmodern Experience, Polity, 2005. There are a number of excellent empirical surveys in the U.S.
My absolute favorite on time is Carmen Lecardi's "Sociologie del tempo". Unfortunately in Italian. Another title coming to my mind is "Time. The Modern and Postmodern Experience" by Helga Nowotny (translated from Germain "Eigenzeit").
