The line
let "SEC_CHECK=DATE2-DATE1"
counts how much time the checking process needs. This is just for information and not necessary for the post-processing of the data. Therefore setting it to
SEC_CHECK=1
does not matter.
I experienced some problem with a similar command sometimes in another script. You may try the following instead of using the
let
command.
SEC_CHECK=$(python -c "print ${DATE2}-${DATE1}")
Anyway, just setting
SEC_CHECK=1
is fine, if you do not need the time information for some reason.
