DateAndTime - Hex to Timestamp conversion

[PolovicJ]

Some OIDs represent timestamp values in DateandTime format as documented in the SNMPv2-TC MIB.

DateAndTime ::= TEXTUAL-CONVENTION
    DISPLAY-HINT "2d-1d-1d,1d:1d:1d.1d,1a1d:1d"
    STATUS       current
    DESCRIPTION
            "A date-time specification.

            field  octets  contents                  range
            -----  ------  --------                  -----
              1      1-2   year*                     0..65536
              2       3    month                     1..12
              3       4    day                       1..31
              4       5    hour                      0..23
              5       6    minutes                   0..59
              6       7    seconds                   0..60
                           (use 60 for leap-second)
              7       8    deci-seconds              0..9
              8       9    direction from UTC        '+' / '-'
              9      10    hours from UTC*           0..13
             10      11    minutes from UTC          0..59

            * Notes:
            - the value of year is in network-byte order
            - daylight saving time in New Zealand is +13

            For example, Tuesday May 26, 1992 at 1:30:15 PM EDT would be
            displayed as:

                             1992-5-26,13:30:15.0,-4:0

            Note that if only local time is known, then timezone
            information (fields 8-10) is not present."
    SYNTAX       OCTET STRING (SIZE (8 | 11))

E.g. spsActiveAlarmLogTime for SilverPeak SD-WAN devices:
iso.3.6.1.4.1.23867.3.1.1.2.1.1.11.1 = Hex-STRING: 07 E7 0A 1C 15 35 34 00 2B 00 00

Using the conversion above the timestamp value would be converted to:
2023-10-28,21:53:52.0,+0:0

Does ktranslate provide a conversion function for DateAndTime format?
I couldn't find anything in the documentation except hextoip and hextoint function.
I tested the latter but it does not provide a correct output.

Not yet but should be possible to add.
