i4dy()

recursive function i4dy

(

IDATE

)

This function converts a date-time with a 2-digit year (YYMMDDHH) to a date-time with a 4-digit year (YYYYMMDDHH) using a windowing technique.

All 2-digit years greater than 40 are assumed to have a 4-digit year beginning with 19 (i.e. 1941-1999), and all 2-digit years less than or equal to 40 are assumed to have a 4-digit year beginning with 20 (i.e. 2000-2040). If the input date-time already contains a 4-digit year, then the function simply returns that value.

Parameters

[in]

IDATE

– integer: Date-time in format of either YYMMDDHH (2-digit year) or YYYYMMDDHH (4-digit year)

Returns

i4dy – integer: Date-time in format of YYYYMMDDHH (4-digit year)
