This component‐private `struct` provides a namespace for a suite of functions used by `BerUtil` to implement BER encoding and decoding operations for time values. Within the definition of this `struct`:

== Synopsis

Declared in `<balber_berutil.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
struct BerUtil_TimeImpUtil;
----

== Description

* *the specification*: > Refers to the August 2015 revision of the ITU‐T Recommendation X.690.

* *the default set of options*: > Refers to a `balber::BerEncoderOptions` value having a > `datetimeFractionalSecondPrecision` attribute of 3 and a > `encodeDateAndTimeTypesAsBinary` attribute of `false`.

See the package level documentation of {`balber`} for a definition of the compact and extended binary formats for date and time values.

| Name| Description
| xref:BloombergLP/balber/BerUtil_TimeImpUtil/getTimeOrTimeTzValue.adoc[`getTimeOrTimeTzValue`] 
| Read the specified `length` number of bytes from the input sequence of the specified `streamBuf` and load to the specified `value` the time and optional time zone value represented by those bytes. Return 0 on success, and a non‐zero value otherwise. The operation succeeds if `length` bytes are successfully read from the input sequence of the `streamBuf` without the read position becoming unavailable, and the bytes contain a valid representation of a time and optional time zone value. See the package‐level documentation of {`balber`} for a description of the decision procedure used to detect the encoding format for a `TimeOrTimeTz` value.
| xref:BloombergLP/balber/BerUtil_TimeImpUtil/getTimeTzValue.adoc[`getTimeTzValue`] 
| Read the specified `length` number of bytes from the input sequence of the specified `streamBuf` and load to the specified `value` the time and time zone value represented by those bytes. Return 0 on success, and a non‐zero value otherwise. The operation succeeds if `length` bytes are successfully read from the input sequence of the `streamBuf` without the read position becoming unavailable, and the bytes contain a valid representation of a time and time zone value. See the package‐level documentation of {`balber`} for a description of the decision procedure used to detect the encoding format for a `bdlt::TimeTz` value.
| xref:BloombergLP/balber/BerUtil_TimeImpUtil/getTimeValue.adoc[`getTimeValue`] 
| Read the specified `length` number of bytes from the input sequence of the specified `streamBuf` and load to the specified `value` the time value represented those bytes. Return 0 on success, and a non‐zero value otherwise. The operation succeeds if `length` bytes are successfully read from the input sequence of the `streamBuf` without the read position becoming unavailable, and the bytes contain a valid representation of a time value. See the package‐level documentation of {`balber`} for a description of the decision procedure used to detect the encoding format for a `bdlt::Time` value.
| xref:BloombergLP/balber/BerUtil_TimeImpUtil/microsecondsSinceMidnightToTime.adoc[`microsecondsSinceMidnightToTime`] 
| Load to the specified `time` the time value represented by the specified `microsecondsSinceMidnight`.

| Load to the specified `time` the time value represented by the specified `millisecondsSinceMidnight`.
| xref:BloombergLP/balber/BerUtil_TimeImpUtil/putTimeTzValue.adoc[`putTimeTzValue`] 
| Write a representation of the specified time and time‐zone `value` to the output sequence of the specified `streamBuf` according to the specified `options`. If `options` is 0, the default set of options is used. Return 0 on success, and a non‐zero value otherwise. This operation succeeds if all bytes in the representation of the `value` are written to the output sequence of the `streamBuf` without the write position becoming unavailable. See the class documentation for a description of the default options. See the package‐level documentation of {`balber`} for a description of the decision procedure used to select an encoding format for the `value`.
| xref:BloombergLP/balber/BerUtil_TimeImpUtil/putTimeValue.adoc[`putTimeValue`] 
| Write a representation of the specified time `value` to the output sequence of the specified `streamBuf` according to the specified `options`. If `options` is 0, the default set of options is used. Return 0 on success, and a non‐zero value otherwise. This operation succeeds if all bytes in the representation of the `value` are written to the output sequence of the `streamBuf` without the write position becoming unavailable.
