About UNIX Timestamp to Windows Filetime Converter
Converts a UNIX timestamp to a Windows Filetime value. A Windows Filetime is a 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601 UTC. A UNIX timestamp is a 32-bit value representing the number of seconds since January 1, 1970 UTC (the UNIX epoch). This operation also supports UNIX timestamps in milliseconds, microseconds and nanoseconds.
Input: text. Output: text.
Format reference: UNIX Timestamp to Windows Filetime background and specification

Input
1276263039529769300
Result
129207366395297693
Parameters
| Parameter | Default value | Input and choices |
|---|---|---|
| Input units | Seconds (s) | Seconds (s), Milliseconds (ms), Microseconds (μs), Nanoseconds (ns) |
| Output format | Decimal | Decimal, Hex (big endian), Hex (little endian) |
Before interpreting the result
Check seconds versus milliseconds and specify the expected timezone. A timestamp identifies an instant; a formatted local date may be ambiguous around daylight-saving transitions.
How to use this page
- Paste your input or open a local file.
- Adjust tool options if needed, then choose Run tool.
- Copy the result or download the original output bytes.
Inputs and results are not added to the public catalogue or saved in the URL. Processing happens in your browser; HTTP Request and DNS over HTTPS send the requests you explicitly run. Files up to 128 MiB can be opened; decompression and image tools may have smaller processing limits. Large results have a shortened preview. Text and HTML downloads use UTF-8; binary downloads preserve output bytes. Pasted text follows browser newline handling; open a file when exact input bytes matter.
