From "The GNU C Library Reference Manual", p. 630:

  time_t
    This is the data type used to represent simple time. Sometimes,
    it also represents an elapsed time. When interpreted as a calendar
    time value, it represents the number of seconds elapsed since
    00:00:00 on January 1, 1970, Coordinated Universal Time.

So I believe "the time (as a time_t integer) in UTC when this event starts"
is perfectly clear.
