Historically, the distinction between GMT and UTC is that a new GMT day begins at noon and a new UTC day begins at midnight. Observational astronomers, who deal in old, even very old observations routinely, still make this distinction carefully. Others, of course, do not.
I am not entirely sure what an ivory-tower instruction is, and STCK[E] may well be one. It is also a convenient, very low-overhead source of high-resolution date-time values that are unique, and thus a convenient component of names that must be unique.
