For your first problem, try - based on the assumption that there's only few time stamps with duplicate seconds and norrmally large gaps in between - this simpler approach, which eliminates the need for a system call to date by adding the epoch time to every line upfront:

Code:

paste <(date +"%s" -f<(cut -d" " -f1,2 data.txt)) data.txt | awk '
$1 in LN        {$1++
                }
                {TM[NR] = $1
                 sub ($1 ".", _)
                 LN[TM[NR]] = $0
                }
END             {for (n=1; n<=NR; n++)  {TMP = TM[n] + 300
                                         DT  = 0
                                         for (SEC=0; SEC<120; SEC++)    {if ((TMP + SEC) in LN) DT = +SEC
                                                                         if ((TMP - SEC) in LN) DT = -SEC
                                                                         if (DT) break
                                                                        }
                                         OUT = LN[TMP+DT]
                                         sub  (/farads./, _, OUT)
                                         $0 = LN[TM[n]] OFS (OUT?OUT:"NA NA")
                                         print
                                        }
                }
