[Question] Timestamp format on json template

[josemnbcamacho]

Hi,

I'm trying to use a timestamp formatter in a json template like

"{ {timestamp: @t:o, level: @l, sourceContext: SourceContext, message: @m} }\n"

Can't manage to get the formatted timestamp, it seems that the parser is not expecting the ":" after "@t".

Is this something supported?

Regards,
José

Hi Jose - unfortunately, this syntax isn't supported; o should be the default format for datetimes, IIRC, so you may not need it at all (?), but otherwise, plugging in a ToString() user-defined function would be the only way to work around this right now:

"{ {timestamp: ToString(@t, 'o'), level: @l, sourceContext: SourceContext, message: @m} }\n"

We might add a ToString(x, format) built-in function to handle these kinds of cases.
