"The people who worked on it took it very seriously," Frenkiel, 64, recalled. "They took a lot of pride in it."
In a twist of historical irony, Frenkiel went on to play a leading role in development of the technology that makes cellphones possible -- the very device that's now instrumental in killing time.
Phone companies have been providing the time to callers since the 1920s. In the early days, live operators read the time off clocks on the wall.
In the 1930s, an Atlanta company called Audichron devised a system for the time to be provided automatically. Audichron leased its technology to phone companies nationwide, often with sponsorship from local businesses.
Time ladies -- and a few gentlemen -- came and went over the years. Then, in the 1950s, a woman named Mary Moore emerged as the nation's leading time-teller.
Her reading of hours, minutes and seconds was delivered in a distinctive if somewhat prissy tone. Moore's odd pronunciation of the numbers 5 ("fiyev") and 9 ("niyun") influenced a generation of operators, much as flying ace Chuck Yeager's West Virginia drawl is said to have been adopted by innumerable airline pilots.
By far the most prominent time lady was Jane Barbe, who succeeded Moore at Audichron in the 1960s. A former big band singer, Barbe (pronounced "Barbie") went on to become the voice of recorded telephone messages in the 1970s and '80s in the United States and elsewhere.
Along with her interpretations of the time and current temperature, Barbe delivered the bad news too, telling you that circuits in a specific area were busy, please try again later, or that your call cannot be completed as dialed.
And who will ever forget her heartbreaking rendition of "I'm sorry, the number you have dialed is no longer in service"?
Barbe died of cancer-related complications in 2003 at age 74. It's estimated that at the height of her fame, Barbe's voice was heard worldwide about 40 million times a day.
AT&T's Britton said the company started using Audichron's machines in 1948 and then switched to a different system manufactured by rival Weatherchron, also of Atlanta, in the 1960s. He was unable to identify the current time lady, saying that perhaps no one at AT&T knows who she is.
Ellis Bryant, the 83-year-old president of Weatherchron, also was unsure whose voice Californians hear when they call time. So he dialed 853-1212 and listened to the recording.
