In Password Safe v3.30 (on Windows 7 64-bit), if I create a new entry, in Flattened List view, the Last Modified and Password Modified fields show N/A, whereas it would be more useful if they showed the creation date/time (ie entry creation is treated as a "modification"). Eg I might want to sort by Password Modified time to find all the passwords that have not been changed recently, but I this doesn't work if the password has only been created the first time and not modified.
Likewise the "password last changed" and "other value last changed" on the Dates and Times page of the Edit Entry dialog should show the creation time if there have been no changes since creation. (Ie show the same date/time as the flat list.)
This appears to be re-occurrence of a bug that I first reported in v3.28 on 2012-03-23 as #657 "Last Modified, Password Modified should be set on creation". (https://sourceforge.net/p/passwordsafe/feature-requests/657/) It was fixed in v3.29, but appears to have been broken again in 3.30
