timeSpanString Grammar

Type Grammar Example Example result
Time span [days.]hours:minutes:seconds[.fractionalSeconds] "0:0:15" When set as a BeginTime, starts the timeline 15 seconds into its timeline duration.
  • In the grammar above, [] indicates optional values, the [] are not literals. The : (colon) and . (period) characters are both literals.
  • Values for hours can be any integer value between 0 and 23 inclusive. Values for minutes and seconds can be any integer value between 0 and 59 inclusive. The value for days can be very large, but does have an unspecified upper bound. The decimal value for fractionalSeconds (with the decimal point included) must be between 0 and 1.

Creating a Duration, KeyTime, RepeatBehavior, or TimeSpan in XAML or in script is only possible through a type conversion syntax when setting a property such as BeginTime that takes one of these types, with the value specified as a string. The string format for specifying a time in each of these types is identical.

The main scenario for working with a TimeSpan as an object in script is to get or set its Seconds property in order to query or change an existing animation value.

Specifying a TimeSpan by only an integer without any time span literal characters such as : or . will result in a RepeatBehavior of that number of days! This is seldom the intended result. Usually you specify animation time spans in seconds. As such, the TimeSpan string must include preceding zero values for hours and minutes, along with the appropriate literal : characters as separators between hours, minutes and seconds. For instance, to specify a TimeSpan of five seconds, the TimeSpan string would be "0:0:5" ("0:0:05" is equivalent).
