You can have as much time as you need. The threads stay around for months and years so you can come back to it when you need.
We do sometimes close PNTs if no one gets back after a long time but now that you have asked for time you can have days or weeks. Since you need , probably, 5 or 8 paragraphs to give the details I guess you need a spare half or so. This time of year is busy and that may be hard to find.
Keep that in mind when replying to comments and questions too. It is better to wait awhile and think through what you are going to say than hurry and not be clear.
