How to set date and time in Azure Cosmos DB?
The recommended format for DateTime strings in Azure Cosmos DB is yyyy-MM-ddTHH:mm:ss.fffffffZ, which follows the ISO 8601 UTC standard. Alternatively, you could use an epoch value to represent time as a number, either in milliseconds or 100 nanosecond ticks.

How to calculate the current month in Cosmos?
You can use the new DateTimePart system function to calculate the current month (or other unit of time) based on a DateTime string. If you have the individual components, you can now build a DateTime string on the fly. Cosmos DB items have a _ts system property.
Are there equality comparisons in Azure Cosmos DB?
Both equality and range comparisons between datetime values in the format yyyy-MM-ddTHH:mm:ss.fffffffZ are supported and will use the index. Because the query engine treats datetime strings as ordinary strings, datetime strings must have constant precision for equality comparisons to be valid.
How to change epoch value in Cosmos DB?
Cosmos DB items have a _ts system property. The _ts value is an epoch value in seconds (not milliseconds) since an item was last modified. To convert the _ts value from seconds to milliseconds or 100 nanosecond ticks, simply multiply by 1,000 or 10,000,000, respectively. You can then convert this value to a DateTime.
How to convert date time to date time offset?
This is shown in the following example, which is run in the US Pacific Standard Time zone. If the DateTime value reflects the date and time in something other than the local time zone or UTC, you can cast it to a value DateTimeOffset and preserve its time zone information by calling the overloaded DateTimeOffset constructor.
What is the unix timestamp in Cosmos DB?
As you can see in the first two serializers, there is a number in the Date constructor. This number is known as the Unix timestamp. Represents the total number of seconds that have elapsed since January 1, 1970. Does not count leap seconds!
