The ASN.1 DATE-TIME type is used to represent a date and time value. Values have the form "YYYY-MM-DDTHH:MM:SS".
When ::= DATE-TIME
DateTime ::= DATE-TIME zero DateTime ::= "1951-10-14T15:30:00"
In BER, the DATE-TIME type value defined in the example above is encoded as follows:
1F21 0E 3139353131303134313533303030
The DATE-TIME type can be constrained by a single value, by type inclusion, by property constraints, and by time point range constraints.
