Changeset 1123 for XIOS/trunk/src/filter/temporal_filter.cpp

Timestamp:

Message:

Instant filter: Optimize the sampling when it is easy to do so.

This way the "xios_field_is_active" function can provide more useful information for the current timestamp even if the user did not specify "freq_op" and "freq_offset".
