FUNCTIONUnder review
Seconds
Seconds() -> nSecondsReturns seconds elapsed since midnight.
Overview
Reads current system time as seconds since midnight. Subtracting readings can become negative across midnight and is affected by clock adjustments. Seconds is therefore not a monotonic timer, unique identifier or complete timestamp. For long jobs, capture date, time and context and choose environment-appropriate timing. (Sources: refs. 1–1.)
Syntax
Seconds() -> nSecondsReturn value
Numeric: seconds of current day.
Commented example

User Function Ed643()

Local nNow := Seconds()
