Class Strftime

java.lang.Object

org.apache.catalina.util.Strftime

public class Strftime
extends Object

Converts dates to strings using the same format specifiers as strftime Notes:

• This does not mimic strftime perfectly. Certain strftime commands, are not supported, and will convert as if they were literals.
• Certain complicated commands, like those dealing with the week of the year probably don't have exactly the same behavior as strftime.
• These limitations are due to use SimpleDateTime. If the conversion was done manually, all these limitations could be eliminated.
• The interface looks like a subset of DateFormat. Maybe someday someone will make this class extend DateFormat.
