How to get the data from the previous scheduled run of BOT?

[kall]

Hi, I have a scenario where I have to get the date and time from the previous scheduled run. For ex: if the last run till May 10 - 6PM then the next run should starts from May 10 - 6:01 PM. How to strore this data in BP for each run so that I can get the start time for the next run? I am thinking of text file, but I wonder there may be better solution then this
