Sib-pair Command: date

Class	Analysis and data manipulation command
Name	date
Arguments	<quantitative_trait> [julian|gregorian|year]

Convert a numeric variable from Julian to Gregorian, Gregorian to Julian, or Gregorian to "decimal" year. The "chronological" Julian date is the number of days since the epoch, usually 1970-01-01 or -4712-01-01. Gregorian dates are represented as 8 (or 9) digit integers of the form of (-)YYYYMMDD. The decimal years are YYYY.x, where the decimal part is the day of year number (from 1...366) divided by the length of that year (365 or 366).

Example:

>> date DOB julian
Converting dates at "DOB" from Gregorian to Julian (epoch="1970-01-01").
