 |
|
In the file "djhora" I have stored the time value "count4d" .
What I want is to recover this value and subtract it to the current time .
If the result is equal to 180 seconds then execute a command.
| Code: |
.....more commands.....
if {![file exists djhora]} {
set count4d [clock seconds]
set temp [open "djhora" w+]
puts $temp "$count4d"
close $temp
}
set temp [open "djhora" r]
set djh [gets $temp]
close $temp
if {[expr {[clock seconds] - $djh}] == 180} { do more commands..... }
|
What is wrong ?

Are you sure you want to use == ?
Whatever you are doing, won't it be difficult to hit it exactly on 180 seconds?
Perhaps you want >= or <= ?
