Check if a file changed once per day

[msi]

We get some reports once a day (Monday till Friday between 22:00 and 24:00) which are placed in single report files on a specific windows system.

Now we would like to check once per day (shortly after 00:00) if these reports were generated.

We created an item "vfs.file.md5sum[C:\dataexchange\blabla.txt]" and a trigger which checks if the md5sum is different from the previous check.

Now our problem/question: How can i configure this item, to just check once a day in a specific timeframe?

If it checks more then once a day, the trigger fires of as the files just changes once.

[msi]

i just wanna post my current solution for this problem.
Maybe someone knows some issues with this solution:

Item: (Interval: 3600)
vfs.file.md5sum[C:\dataexchange\blabla.txt]

Trigger:
{host:vfs.file.md5sum[C:\dataexchange\blabla.txt].last(0)}#{host:vfs.file.md5sum[C:\dataexchange\blabla.txt].last(#24)} & {host:vfs.file.md5sum[C:\dataexchange\blabla.txt].dayofweek(0)}<6

So this trigger should only fire off Monday till Friday, when the file didn't change the last 24 hours (+/- 1 hour)

[trikke]

Other solution would be (untested )

{host:vfs.file.md5sum[C:\dataexchange\blabla.txt].diff(0)} > 0 & ( {host:vfs.file.md5sum[C:\dataexchange\blabla.txt].time(0)} > 220000 & {host:vfs.file.md5sum[C:\dataexchange\blabla.txt].time(0)} < 235900 )

my first configuration was almost like that, but:
- the exact time of the report varies (just a few minutes normally)
- assume an intervall 3600 for your suggestion:
report: 22:10 h
itemcheck: 22:15 and 23:15
trigger: first time ok, second problem (although the report was done this day)

- assume an intervall 7200 for your suggestion:
report: 22:10 h
itemcheck: 22:05
trigger: problem (although the report was done this day)
