Ejemplos
Editor de código (JavaScript)
// Defines a base date/time for the following examples.
var BASE_DATE = ee.Date('2020-7-1T13:00', 'UTC');
print(BASE_DATE, 'The base date/time');
// Demonstrates basic usage.
print(BASE_DATE.advance(1, 'week'), '+1 week');
print(BASE_DATE.advance(2, 'years'), '+2 years');
// Demonstrates that negative delta moves back in time.
print(BASE_DATE.advance(-1, 'second'), '-1 second');
