offsetFrom(DateTimeComponents)

Method Detail

parseDateTime

public static DateTimeComponents parseDateTime(java.lang.String string)

Parse a string in ISO-8601 format to build a date/time.

The supported formats are all date formats supported by DateComponents.parseDate(String) and all time formats supported by TimeComponents.parseTime(String) separated by the standard time separator 'T', or date components only (in which case a 00:00:00 hour is implied). Typical examples are 2000-01-01T12:00:00Z or 1976W186T210000.

Parameters:

string - string to parse

Returns:

a parsed date/time

Throws:

java.lang.IllegalArgumentException - if string cannot be parsed

offsetFrom

public double offsetFrom(DateTimeComponents dateTime)

Compute the seconds offset between two instances.

Parameters:

dateTime - dateTime to subtract from the instance

Returns:

offset in seconds between the two instants (positive if the instance is posterior to the argument)
