The timestamp held by this entry is returned in one of three
formats: as a standard UNIX timestamp (default), as a fractional
Julian Day Count, or as a string.
public getValue ( $type = self::UNIX_TIMESTAMP ) : integer | ||
Résultat | integer | the timestamp held by this entry in the correct form as indicated by the type argument. For {@link UNIX_TIMESTAMP} this is an integer counting the number of seconds since January 1st 1970, for {@link EXIF_STRING} this is a string of the form 'YYYY:MM:DD hh:mm:ss', and for {@link JULIAN_DAY_COUNT} this is a floating point number where the integer part denotes the day count and the fractional part denotes the time of day (0.25 means 6:00, 0.75 means 18:00). |
