Namespace: GSF
Assembly: GSF.Core (in GSF.Core.dll) Version: 2.4.218-beta+101eee949414e414795e55a6e73d88938f0177b8
Syntax[SerializableAttribute] public class NtpTimeTag : TimeTagBase
The NtpTimeTag type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | NtpTimeTag(Decimal) | Creates a new NtpTimeTag, given number of seconds since 1/1/1900. |
| NtpTimeTag(Ticks) | Creates a new NtpTimeTag, given specified Ticks. |
| NtpTimeTag(UInt64) | Creates a new NtpTimeTag, given 64-bit NTP timestamp. |
 | NtpTimeTag(SerializationInfo, StreamingContext) | Creates a new NtpTimeTag from serialization parameters. |
| NtpTimeTag(UInt32, UInt32) | Creates a new NtpTimeTag, given number of seconds and fractional seconds since 1/1/1900. |
Properties| Name | Description | |
|---|---|---|
 | BaseDateOffsetTicks |
Gets ticks representing the absolute minimum time of this timetag implementation.
(Inherited from TimeTagBase) |
| Timestamp | Gets 64-bit NTP timestamp. |
| Value |
Gets or sets number of seconds (including any fractional seconds) since base time.

(Inherited from TimeTagBase) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
 | FromTicks | Gets 64-bit NTP timestamp given timestamp in Ticks. |
| GetBaseDateOffsetTicks(Decimal) | Gets proper NTP offset based on seconds value, see RFC-2030. |
| GetBaseDateOffsetTicks(Ticks) | Gets proper NTP offset based on timestamp value, see RFC-2030. |
| GetBaseDateOffsetTicks(UInt32) | Gets proper NTP offset based on most significant byte on seconds value, see RFC-2030. |
| GetHashCode |
Serves as a hash function for the current TimeTagBase.
(Inherited from TimeTagBase) |
| GetObjectData |
Populates a SerializationInfo with the data needed to serialize the target object.
(Inherited from TimeTagBase) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| ToDateTime |
Returns standard .NET DateTime representation for timetag.
(Inherited from TimeTagBase) |
| ToString |
Returns basic textual representation for timetag.
(Inherited from TimeTagBase) |
| ToString(IFormatProvider) |

(Inherited from TimeTagBase) |
| ToString(String) |
Returns textual representation for timetag in the specified format.
(Inherited from TimeTagBase) |
| ToString(String, IFormatProvider) |
Returns textual representation for timetag in the specified format using
the specified provider.
(Inherited from TimeTagBase) |
Fields| Name | Description | |
|---|---|---|
 | AlternateBaseTicks | Number of ticks since since 2/7/2036 at 6h 28m 16s UTC when MSB is set. |
| BaseTicks | Number of ticks since 1/1/1900. |
Extension Methods| Name | Description | |
|---|---|---|
 | GetEnumValueOrDefault |
Gets the enumeration constant for value, if defined in the enumeration, or a default value.
(Defined by EnumExtensions) |
| GetEnumValueOrDefaultT |
Gets the enumeration constant for this value, if defined in the enumeration, or a default value.
(Defined by EnumExtensions) |
Remarks
As recommended by RFC-2030, all NTP timestamps earlier than 3h 14m 08s UTC on 20 January 1968
are reckoned from 6h 28m 16s UTC on 7 February 2036. This gives the NtpTimeTag
class a functioning range of 1968-01-20 03:14:08 to 2104-02-26 09:42:23.
