Thanks. Both fixed in the newly released version.

${if match{$tod_log}{\N^.{11}(\d\d)\N}{$1}}

expands to the hour of the day. Thus, a condition that yields "yes"
between the hours of 2 am and 8 am is:

condition = ${if and                                                  \
                 {                                                    \
                   { >                                                \
                     {${if match{$tod_log}{\N^.{11}(\d\d)\N}{$1}}}    \
                     {2}                                              \
                   }                                                  \
                   { <                                                \
                     {${if match{$tod_log}{\N^.{11}(\d\d)\N}{$1}}}    \
                     {8}                                              \
                   }                                                  \
                 }                                                    \
                 {yes}{no}}
