Are you sure the ATIS wasn't saying the 'this is information tango'? The ATIS information is identified by a letter (A thru to Z to keep it simply for us controllers), incrementing each time the ATIS is changed. There would be no reference to the time as 'tango' just as, certainly with our ATIS, is isn't called 'zulu' as it is always zulu time and saying it would be superfluous.
