At the risk of assuming something, I suspect that the 26 character TOD is a formatted string like this " YYYY/MM/DD.HH:MM:SS.XXXXXX" The XXXXXX on the end would be microseconds.

It rather depends on what this 26-character thing is, I think. Also keep in mind that all TOD values since May 11, 1971 at about noon have their high bit on, and so can lead to trouble if you or your programming language insists on treating the whole thing as a signed binary integer. Shifting the value(s) right by 12 bits addresses this potential problem at the same time as it converts to microseconds, which are usually both accurate enough for most purposes, and easier to understand and sanity check than are the raw numbers.
