Here's some of the time formats that Truxton can handle. Wikipedia has a better list. The Truxton software uses FILETIME for all time calculations.
| Epoch | Type |
|---|---|
15 Oct 1582
|
UUID Type 1 |
01 Jan 1601
|
Windows FILETIME Chrome |
30 Dec 1899
|
Windows COM |
01 Jan 1970
|
Unix Time Firefox |
01 Jan 2001
|

Apple Cocoa Core
Cocoa Core (aka NSDate) is the number of seconds (32-bit value) since 01 Jan 2001. The 64-bit version is the number of nanoseconds since 01 Jan 2001.
Chrome
Chrome stores the time as a 64-bit integer representing the number of microseconds since 01 Jan 1601.
Firefox
Firefox (PRTime) stores the time as a 64-bit integer representing the number of microseconds since 01 Jan 1970.
Unix Time
This is a 32-bit integer holding the number of clock ticks since 01 Jan 1970. You will see this value in a variety of ticks.
Hints
The Unix epoch can be stored in several different clock ticks.
| Digits | Tick Units |
|---|---|
| 10 | One Second |
| 13 | One Millisecond |
| 16 | One Microsecond |
| 19 | One Nanosecond |
UUID
A 60-bit integer holding the number of 100-nanosecond clock ticks since 15 Oct 1582.
Windows COM
Windows COM stores date time in a double (floating point) number representing the number of days since 30 Dec 1899.
Windows FILETIME
A 64-bit integer containing the number of 100-nanosecond clock ticks since 01 Jan 1601.
