Class GitDateParser

  org.eclipse.jgit.util.GitDateParser

public class GitDateParser
extends Object

Parses strings with time and date specifications into Date. When git needs to parse strings specified by the user this parser can be used. One example is the parsing of the config parameter gc.pruneexpire. The parser can handle only subset of what native gits approxidate parser understands.

parse

public static Date parse(String dateStr,
                         Calendar now)
                  throws ParseException

Parses a string into a Date. Since this parser also supports relative formats (e.g. "yesterday") the caller can specify the reference date. These types of strings can be parsed:

• "never"
• "now"
• "yesterday"
• "(x) years|months|weeks|days|hours|minutes|seconds ago"
  Multiple specs can be combined like in "2 weeks 3 days ago". Instead of ' ' one can use '.' to seperate the words
• "yyyy-MM-dd HH:mm:ss Z" (ISO)
• "EEE, dd MMM yyyy HH:mm:ss Z" (RFC)
• "yyyy-MM-dd"
• "yyyy.MM.dd"
• "MM/dd/yyyy",
• "dd.MM.yyyy"
• "EEE MMM dd HH:mm:ss yyyy Z" (DEFAULT)
• "EEE MMM dd HH:mm:ss yyyy" (LOCAL)

Parameters:

dateStr - the string to be parsed

now - the base date which is used for the calculation of relative formats. E.g. if baseDate is "25.8.2012" then parsing of the string "1 week ago" would result in a date corresponding to "18.8.2012". This is used when a JGit command calls this parser often but wants a consistent starting point for calls.
If set to null then the current time will be used instead.

Returns:

the parsed Date

Throws:

ParseException - if the given dateStr was not recognized
