public string
DaylightName
Gets the display name for the current time zone's daylight saving time.
public string
DisplayName

public bool
SupportsDaylightSavingTime
Gets a value indicating whether the time zone has any daylight saving time rules.

Methods

public bool
Equals​(object obj)
obj A second object to compare with the current object.
Returns <see langword="true" /> if <paramref name="obj" /> is a <see cref="T:System.TimeZoneInfo" /> object that is equal to the current instance; otherwise, <see langword="false" /> .
Determines whether the current <see cref="T:System.TimeZoneInfo" /> object and another object are equal.
public bool
Equals​(TimeZoneInfo other)
other A second object to compare with the current object.
Returns <see langword="true" /> if the two <see cref="T:System.TimeZoneInfo" /> objects are equal; otherwise, <see langword="false" /> .
Determines whether the current <see cref="T:System.TimeZoneInfo" /> object and another <see cref="T:System.TimeZoneInfo" /> object are equal.
public AdjustmentRule[]
GetAdjustmentRules​()
Returns An array of objects for this time zone.
Retrieves an array of <see cref="T:System.TimeZoneInfo.AdjustmentRule" /> objects that apply to the current <see cref="T:System.TimeZoneInfo" /> object.
public TimeSpan[]
GetAmbiguousTimeOffsets​(DateTime dateTime)
dateTime A date and time.
Returns An array of objects that represents possible Coordinated Universal Time (UTC) offsets that a particular date and time can be mapped to.
Returns information about the possible dates and times that an ambiguous date and time can be mapped to.
public TimeSpan[]
GetAmbiguousTimeOffsets​(DateTimeOffset dateTimeOffset)
dateTimeOffset A date and time.
Returns An array of objects that represents possible Coordinated Universal Time (UTC) offsets that a particular date and time can be mapped to.
Returns information about the possible dates and times that an ambiguous date and time can be mapped to.
public int
GetHashCode​()
Returns A 32-bit signed integer that serves as the hash code for this <see cref="T:System.TimeZoneInfo" /> object.
Serves as a hash function for hashing algorithms and data structures such as hash tables.
public TimeSpan
GetUtcOffset​(DateTime dateTime)
dateTime The date and time to determine the offset for.
Returns An object that indicates the time difference between the two time zones.
Calculates the offset or difference between the time in this time zone and Coordinated Universal Time (UTC) for a particular date and time.
public TimeSpan
GetUtcOffset​(DateTimeOffset dateTimeOffset)
dateTimeOffset The date and time to determine the offset for.
Returns An object that indicates the time difference between Coordinated Universal Time (UTC) and the current time zone.
Calculates the offset or difference between the time in this time zone and Coordinated Universal Time (UTC) for a particular date and time.
public bool
HasSameRules​(TimeZoneInfo other)
other A second object to compare with the current <see cref="T:System.TimeZoneInfo" /> object.
Returns <see langword="true" /> if the two time zones have identical adjustment rules and an identical base offset; otherwise, <see langword="false" /> .
Indicates whether the current object and another <see cref="T:System.TimeZoneInfo" /> object have the same adjustment rules.
public bool
IsAmbiguousTime​(DateTime dateTime)
dateTime A date and time value.
Returns <see langword="true" /> if the <paramref name="dateTime" /> parameter is ambiguous; otherwise, <see langword="false" /> .
Determines whether a particular date and time in a particular time zone is ambiguous and can be mapped to two or more Coordinated Universal Time (UTC) times.
public bool
IsAmbiguousTime​(DateTimeOffset dateTimeOffset)
dateTimeOffset A date and time.
Returns <see langword="true" /> if the <paramref name="dateTimeOffset" /> parameter is ambiguous in the current time zone; otherwise, <see langword="false" /> .
Determines whether a particular date and time in a particular time zone is ambiguous and can be mapped to two or more Coordinated Universal Time (UTC) times.
public bool
IsDaylightSavingTime​(DateTime dateTime)
dateTime A date and time value.
Returns <see langword="true" /> if the <paramref name="dateTime" /> parameter is a daylight saving time; otherwise, <see langword="false" /> .
Indicates whether a specified date and time falls in the range of daylight saving time for the time zone of the current <see cref="T:System.TimeZoneInfo" /> object.
public bool
IsDaylightSavingTime​(DateTimeOffset dateTimeOffset)
dateTimeOffset A date and time value.
Returns <see langword="true" /> if the <paramref name="dateTimeOffset" /> parameter is a daylight saving time; otherwise, <see langword="false" /> .
