Computer-based system and method for inferring a four-digit calendar year from a date expressed in a format having a two-digit calendar year |
摘要 |
A computer-based system (10) for inferring an output date expressed in a format having a four-digit calendar year from a historical input date expressed in a format having a two-digit calendar year includes a converter (16) that receives from an application program (12) an input date parameter (52) corresponding to the input date and specifying a two-digit input year value. The converter (16) also receives from an operating system (18) a current system date recognizable to the converter (16) in a format having a four-digit calendar year, the first two digits of which have a current century value and the last: two digits of which have a current two-digit value. If the input year value is less than or equal to the current two-digit value, the converter (16) infers the first two digits of the four-digit calendar year of the output date to be the current century value. The converter (16) may infer the first two digits of the four-digit calendar year of the output date to be "19" if the input year value is not less than or equal to the current two-digit value.
