Parameters:

d - Date that defines year, month and day for time.

Returns:

A Date that is combination of specified Date and Time

toString

public String toString()

Returns the String representation of Time. Formats the time in hhmmss.sss format used in NMEA 0183 sentences. Seconds are presented with three decimals regardless of precision returned by getSeconds().

Overrides:

toString in class Object

toISO8601

public String toISO8601()

Returns the ISO 8601 representation of time (hh:mm:ss+hh:mm).
