A simple and non-intrusive library for all your epoch needs
using Epoch.net;
...
var timestamp = EpochTime.Now;
...Epoch is shorthand for Unix epoch time or as it is also known POSIX time.
Short version: The number of seconds since 1970-01-01T00:00:00Z without leap seconds.
Long version: unix time
With .net core working on all major operating systems and most of them using POSIX to denote time and timestamps. Not to mention the myriad of 3rd party tools, using POSIX time internally. The need for a working and tested implementation became clearer and clearer. Additionally I did not want to write this logic in an inferior form in many of my applications. So this little library was written.
Its sole purpose is to make the work with these unix timestamps as easy as possible.
For this purpose this library contains extension methods that build upon the existing DateTime, TimeSpan, int and long types.
| Term | Description |
|---|---|
| EpochTime | Represents a POSIX time instance exact to the second |
| EpochTimestamp | The number of seconds since 1970-01-01T00:00Z |
| LongEpochTime | Represents a POSIX time instance exact to the millisecond |
| LongEpochTimestamp | The number of milliseconds since 1970-01-01T00:00Z |
The initial difference was precision. EpochTime will only be accurate to the nearest second on the other hand LongEpochTime is accurate to the millisecond. From this precision difference I decided to differentiate then by their underlying base type.
EpochTime is based on int32 / int
LongEpochTime is based on int64 / long
❗This is sadly implies that if you get a POSIX timestamp from somewhere you, the developer, have to know if it is representing milliseconds or seconds!
| Unit | Min value | Max value |
|---|---|---|
| EpochTimestamp | -2147483648 | 2147483647 |
| LongEpochTimestamp | -922337203685477 | 922337203685477 |
📝 Note: The range of the LongEpoch is theoretically limited only by the range of int64.
- EpochTime a second precise POSIX time wrapper
- LongEpochTime a millisecond precise POSIX time wrapper
- Extension methods for build in time handling classes:
- DateTime
- TimeSpan
- DateOnly
- TimeOnly
- Fully tested ;)
The preferred way of integrating the library is to use the nuget package. This is easily done be either:
dotnet add package Epoch.netor
Install-Package Epoch.netAfter the package is added to the project add the using directive:
...
using Epoch.net;
...Done 🎉
