The data used for updating the RRD was acquired at a certain
time. This time can either be defined in seconds since
1970-01-01 or by using the letter 'N', in which case the update
time is set to be the current time. Negative time values are

The remaining elements of the argument are DS updates. The
order of this list is the same as the order the data sources
were defined in the RRA. If there is no data for a certain
data-source, the letter U\bU (e.g., N:0.1:U:1) can be specified.
