I think this might work for you as long as you aren't going to conduct any calculations off of the time stamp.
Create a separate table with the following fields (change field names to suite your purposes):
Time Stamp: formatted as simple text
Status: formatted as either text or memo
Work Order Number: formatted as either text or number (depending on your work order number format)
Log Number: formatted as AutoNumber and set as the Primary Key for the table
In Field Properties for the Time Stamp field, either use Expression Builder to build the following expression or simply manually enter it as the Default Value.
=Date() & " " & Time()
Notes:
1. No space between the (=) and Date.
2. In the Date() expression, thereis no space between Date and (). No space between (). Same for Time() expression.
3. 1 blank space prior to and after each (&).
4. The number of blank spaces between the quotation marks determines the seperation between the date and time.
By setting this expression up as the field default value, it will automatically be entered when a new record is created (whenever you create a new status entry).
Join this table to whatever other table you a use to enter other information relevant to the work order using the Work Order number field. Set the relationship as one-to-many (you will only have a single unique work order but can have many status entries relating to that work order).
Hope this helps.
