Logical. If TRUE, return the date in milliseconds from the Unix Epoch (1970-01-01 00:00:00 UTC). Otherwise, return the date as a POSIXct object. By default FALSE. |
eedate_to_rdate is essential to avoid potential errors that
might appear when users call to retrieve dates. Currently,
R integer only supports 32 bit signed (such integers can only
count up to about 2 billion). This range is notably insufficient for dealing
with GEE date objects represented by timestamps in milliseconds since the
UNIX epoch. eedate_to_rdate uses Python in the backend to obtain the
date and convert it in float before exporting to R.
eedate_to_rdate will return either a numeric timestamp or
a POSIXct object depending on the timestamp argument.

ee_get_date_img(),
