#### TimesDates.jl: work with nanosecond resolved times.

- the types play very well together and with others
- the calculations defer to those of Dates, TimeZones
- the perspective is already familiar, and easy to use

| _this type is like_ | _a more finely resolved_ |
| TimeDate | Dates.DateTime |

| TimeDateZone | TimeZones.ZonedDateTime |

#### install

This package requires Julia v0.7-, please run Pkg.update() first.

```julia-auto
using Pkg; Pkg.add("TimesDates")
using TimesDates, TimeZones, Dates

```

The [README](https://github.com/JeffreySarnoff/TimesDates.jl/blob/master/README.md) provides an introduction with utilitarian examples and a note on the design.

A good guide to transparent work with Dates and TimeZones is provided by the [test file](https://github.com/JeffreySarnoff/TimesDates.jl/blob/master/test/runtests.jl).

Great package!  
Any chance of seeing these minimal changes included in Base.Dates ?

The package branch master has been renamed main.  
If you have a local copy …

```julia
git branch -m master main
git fetch origin
git branch -u origin/main main
git remote set-head origin -a

```
