1	data(UN_time)

A data frame with 1034 observations on the following 4 variables.

TimeID: Time identifier.
TLabel: Label of the time, with minimum values of 1950 and 1950-1955, and maximum values of 2399, 2400 and 2400-2405.
TDate: Equal to TLabel if it is a single year, or the starting year of TLabel, if it is an interval.
Tinterval: Length of the time interval, or zero, if it is a single year.

For 5-year period data, fertility rates are defined from 1 July of year (t) to 1 July of year (t+5), with 1 January of year (t+3) as exact mid-date. This means for example that data for 2000-2005, refer to the period between 2000.5 and 2005.5, with 2003.0 as exact mid-point.
