UnixTime · .NET & Cross-platform Development

.NET ticks on your Mac. Readable at a glance.

When your service returns ticks, you need a converter that knows their epoch. Select .NET Ticks in UnixTime and translate individual values with the menu bar icon or ⌘⌃U.

Convert .NET ticks on Mac: preserve 100-nanosecond resolution and display custom date formats without rounding.

Sound familiar?

Less friction when working with time.

Ticks are not Unix nanoseconds

Choose .NET Ticks as the source format instead of interpreting the number solely by its length.

Windows returns FILETIME

For a FILETIME value, switch explicitly to Windows FILETIME / LDAP.

The contract calls for a readable date

Copy the result as ISO 8601 UTC to compare it with interface data.

Your next time value

Three steps to a readable result.

Choose the ticks format
Set .NET Ticks as the default timestamp format in UnixTime settings.
Convert an individual value
Copy the ticks value, then click the menu bar icon or press ⌘⌃U.
Compare it with the API date
Paste the UTC result into your debug notes and compare the time.

The example uses UTC. Your output follows your selected default formats. Direct insertion via a shortcut requires macOS Accessibility permission.

Precision for log analysis & forensics

Does not round. Down to the nanosecond.

Convert Unix timestamps with nanosecond precision. UnixTime preserves fractional seconds from numeric input timestamps. No floating-point rounding. No zeros recreated from whole seconds.

Example: Unix nanoseconds, a custom date format and the UTC time zone. Source accuracy still matters; conversion does not invent extra measurement precision.

Custom formats: 3, 6 or 9 digits.

Pattern	Display precision	Example
`SSS`	Milliseconds (3 digits)	`.123`
`SSSSSS`	Microseconds (6 digits)	`.123456`
`SSSSSSSSS`	Nanoseconds (9 digits)	`.123456789`

Use, for example yyyy-MM-dd HH:mm:ss.SSSSSSSSS. Nine digits display the full nanosecond fraction. Three or six display only the leading digits, without rounding up. A pattern without S does not display fractional seconds.

Keyboard shortcuts on your Mac

Keep typing. Your timestamp is ready.

Copy your time value and click the menu bar icon — or press ⌘⌃U. Reassign any of the four shortcuts to suit your workflow.

⌘⌃U: Convert the clipboard
⌘⌃V: Convert and replace your selection
⌘⌃⌥V: Append the conversion to the original
⌘⌃N: Insert the current timestamp

⌘ = Command · ⌃ = Control · ⌥ = Option. Inserting, replacing and appending text require macOS Accessibility permission and an editable text field. Clipboard conversion does not require that permission.

Before you start

Your questions, answered.

Does the app detect DateTime.Kind or an offset?

A bare ticks value does not contain that information. Check whether the source value represents UTC or local time. This example uses UTC.

Are 100-nanosecond fractions preserved?

Yes. Reading .NET ticks preserves their 100-nanosecond resolution. SSSSSSSSS displays nine fractional digits; the last digit of a ticks-based value is zero.

How do I display fractional seconds?

Use a custom date format: SSS for milliseconds (3 digits), SSSSSS for microseconds (6 digits), or SSSSSSSSS for nanoseconds (9 digits). Choose nine digits to display all available nanoseconds. Shorter patterns show only the leading digits, without rounding up.

What do I need to use keyboard shortcuts?

UnixTime must be running on your Mac. All shortcuts can be reassigned. Replacing, inserting and appending text require macOS Accessibility permission and an editable destination. Converting the clipboard with the menu bar icon or ⌘⌃U does not require that permission. ⌘ means Command, ⌃ means Control and ⌥ means Option (Alt).

Does it work offline?

Yes. Conversion, the date generator and history run locally. They need neither an account nor an internet connection. UnixTime is a one-time purchase without a subscription; see the Mac App Store for the current price.
