DAYTIME(UCB) — UNIX Programmer’s Manual
NAME
daytime − give the time to human-reasonable accuracy
SYNOPSIS
daytime
DESCRIPTION
Daytime prints out in the English the current time of day, accurate to the nearest fifteen minutes. Many people find this type of abstraction useful, since it doesn’t really matter to them that it’s 16:19 when all they wanted to know is that it’s "Quarter past four."
BUGS
Daytime depends on the user to determine whether it’s currently night or day.
