`get_date_band`

Get the date of an image, compute how many units (for example day) has ellpsed since the epoch (1970-01-01) and set it to a band (called date) and a property (called unit_since_epoch, for example, day_since_epoch)



In [5]:

In [6]:

`date_since_epoch`

Given an ellapsed time since epoch (for example the result of get_date_band) compute what day it is



In [7]:

date_since_epoch = tools.date.dateSinceEpoch(image_date)

`unit_since_epoch`

Return the number of unit (for example, day) since the epoch (1970-1-1)
