This object provides the ability to read and write the time stored in the real-time clock (RTC). It can also be used to read and write the time-zone setting. The JavaScript equivalent is systemtime.

Dates up to January 1, 2038 are supported.

ifUserData

SetUserData(user_data As Object)

Sets the user data that will be returned when events are raised.

GetUserData() As Object

Returns the user data that has previously been set via SetUserData(). It will return Invalid if no data has been set.

ifMessagePort

SetPort(port As roMessagePort)

Posts messages of the type roNetworkTimeEvent to the attached message port.

ifSystemTime

GetLocalDateTime() As roDateTime

Returns the current time from the RTC (modulated using the current time zone) as an roDateTime instance.

GetUtcDateTime() As roDateTime

Returns the current time from the RTC (modulated using the UTC/GMT time zone) as an roDateTime instance.

GetZoneDateTime(timezone_name As String) As Object

Returns the current time from the RTC (modulated using the specified time zone) as an roDateTime instance. Supported time zones are listed below.

SetLocalDateTime(local_DateTime As roDateTime) As Boolean

Specifies a new time for the RTC using the current time zone.

SetUtcDateTime(utc_DateTime As roDateTime) As Boolean

Specifies a new time for the RTC using the UTC/GMT time zone.

GetTimeZone() As String

Returns the current time-zone setting of the player. A POSIX: value is appended to the beginning of the string if the time zone has been set using the POSIX format.

SetTimeZone(zone_name As String) As Boolean

Specifies a new time-zone setting for the player (supported time zones are listed below). Alternatively, a POSIX formatted time zone can be applied by appending a POSIX: value to the beginning of the string.

The following code specifies a POSIX-formatted time zone:

t = CreateObject("roSystemTime") t.SetTimeZone("POSIX:GMT-0BST-1,M3.5.0/1:00,M10.5.0/2:00")
IsValid() As Boolean

Returns True if the system time is set to a valid value. The time can be set from the RTC or with NTP.

GetLastNetworkTimeResult() As roAssociativeArray

Returns an associative array containing information about the last attempt to set the time via the network:

  • success_timestamp: A value indicating when the clock was last set successfully via the network. This value is zero if the clock has never been set successfully via the network.

  • attempt_timestamp: A value indicating when the last attempt was made to set the clock via the network. This value is zero if no attempt has been made yet.

  • failure_reason: If the last attempt to set the clock via the network failed, this string will contain an error message. If the last attempt was successful, this string will be empty.

In this associative array, "timestamp" refers to the number of seconds since the player booted. This value can be compared against the total uptime of the player, which is retrieved by calling UpTime(0).
