  • All Implemented Interfaces:
    Serializable, SchemaObject
    public final class UtcTimeSyntaxChecker
extends SyntaxChecker
    A SyntaxChecker which verifies that a value is a UTC time according to RFC 4517.

    From RFC 4517 : 

     UTCTime         = year month day hour minute [ second ] [ u-time-zone ]
 u-time-zone     = %x5A          ; "Z" | u-differential
 u-differential  = ( MINUS | PLUS ) hour minute

 year    = 2(%x30-39)            ; "00" to "99"
 month   = ( %x30 %x31-39 )      ; "01" (January) to "09"
           | ( %x31 %x30-32 )    ; "10" to "12"
 day     = ( %x30 %x31-39 )      ; "01" to "09"
           | ( %x31-32 %x30-39 ) ; "10" to "29"
           | ( %x33 %x30-31 )    ; "30" to "31"
 hour    = ( %x30-31 %x30-39 ) 
           | ( %x32 %x30-33 )    ; "00" to "23"
 minute  = %x30-35 %x30-39       ; "00" to "59"

 second  = ( %x30-35 %x30-39 )   ; "00" to "59"

 g-time-zone = %x5A              ; "Z"
               | g-differential
 g-differential = ( MINUS / PLUS ) hour [ minute ]
 MINUS   = %x2D  ; minus sign ("-")
 
 From RFC 4512 :
 PLUS    = %x2B ; plus sign ("+")
