Engaged in software development for so many years, usually also accumulated some convenient to their own rapid development of the help class, has been thinking of what way to share out, so there is this series of articles, the back I will be "open source - Ideal library" series of articles to share some of what I think is more mature, more convenient, better code, if you feel that there is a reference to the place can be integrated into their own public codebase, and at the same time I will also be released as a Nuget package for direct download and use.
Mainly includes: public, documentation, ORM, SqlSugar, timed tasks, Redis, Mqtt, SignalR and other library packages, the back may also be appropriate to delete .
Today we are going to share the relevant wrappers in the public libraries for time conversions, mainly about the interconversion between local and UTC dates, times and timestamps and strings.
01Date time to timestamp (seconds)
This method is to convert the date time DateTime to a 10-bit timestamp, i.e. a second timestamp, with the following code:
/// <summary>
/// datetime to timestamp（unit of angle or arc equivalent one sixtieth of a degree）
/// </summary>
/// <param name="dateTime">Date Time</param>
/// <returns>timestamp（unit of angle or arc equivalent one sixtieth of a degree）</returns>
public static long ToUnixTimestampBySeconds(this DateTime dateTime)
{
var dto = new DateTimeOffset(dateTime);
return ();
}
02, datetime to timestamp (milliseconds)
This method is to convert the datetime DateTime to a 13-bit timestamp, i.e. a millisecond timestamp, with the following code:
/// <summary>

I'll upload the library to Nuget later, so you can search for it and use it directly.
classifier for sums of money: The test method code as well as the sample source code have been uploaded to the code repository for those who are interested./hugogoos/Ideal
